A quick summary of term 4

Another term has ended. It was a tough one. I started well, but lost momentum due to a week of going back home for Tết. And took time to gain back momentum after that, because I had to play catch with the content. And then I had to put my research on hold to to a side project. The good thing was that this project turned out to be interesting and I learned quite a fair bit. On top of school and research,  I’m also participating in the EVA Challenge, predicting rainfall extreme. And then the exam came. In previous terms, I had always felt that I’ve learned the material well and was not worried at all at the exam. But not this time. Anyways, the exams were okay. The term ended with a fun pizza-and-salad lunch with other PhD students. We ended up talking a lot. It was great to catch up.

And now, it’s time for the Quals, after which it’ll be full-time research. But during the next 3 weeks of Quals prepration, I’m still gonna keep up with my grand tradition of doing research every Friday—it’s my version of the 20-mile rule.

 

2016 is over, and I’m a 30-year-old second-year PhD student with a 1-year-old baby

I celebrated my thirtieth birthday one day early with some wonderful grilled lamb ribs, air flown from Australia by my brother-in-law, and cooked to perfection by my lovely wife. We also had our favourite tiramisu, also made by her. I spent the last 3 weeks at home, recovering from a tough term, looking after my son, and doing things around the house. We also enjoyed a staycation, the itinerary of which revolves around the baby, of course. Last 3 weeks was such a good break from study that I actually started to miss school last couple of days. Tomorrow, on my thirtieth birthday, I’m going back to school, ready for a new year.

Being a January baby has its advantage: I can do the year-end reflection and the new-age reflection at the same time. 2016 to me was a very special year: it’s the first year being a dad, it’s the first year of my PhD, and it’s my thirtieth year of life. Well, the last one is just a numerical significance, but the first two are really important milestones.

I reflected on my first PhD year in the previous post. I have two important updates today. The first one is that I bagged another two As last term, which means I’ve got five As in a row. I have never been this good in my entire life (always a good-but-not-so-brilliant student in my undergraduate and masters). It turned out that I did well enough in the Optimization & Control class that the final did not affect it too much (and the final was tough for everyone anyways). Grades aside, the most important aspect of last term was that I received a lot of positive feedback for my teaching assistantship. The students said I was helpful, responsible, knowledgeable, dedicated, enthusiastic, passionate, among other things. One student said I was the best TA he’d seen. Another student said he thought I would be a good lecturer (well, he just struck my sweet spot). And it seems that apart from the things a TA should do, my most important contribution to them is my industry experience, which I shared a lot in and out of class. Not bad at all for a first timer.

I’m certainly proud of my first year as a PhD student, but I’m even more proud of my first year being a dad. It’s the most fulfilling thing I’ve ever done. All the diaper changing, putting the baby to sleep, carrying him everywhere in the carrier, and playing with him were all quite an experience. But I think my unique dad thing was that I made a lot of toys and things for him. Let’s start with the handy-man stuff, and then I’ll showcase the toys.

Before he was born, I painted his entire room.

I made a mirror and stand for him to stand up

Mirror

In his room, I installed a shelf to keep all the non-baby-friendly stuff off limit, and it even comes with a set of lights that warm up the entire room before bedtime:

He started to crawl all over the house and opened cabinet doors, so I had to baby-proof them. But I still want to let him play his opening-closing game. I put 7 pieces of wood together (from old kitchen door and shelves) to make a cabinet for him. It also acts as a garage for his cars (aka walkers)

Now let’s talk about the toys. Here’s a little lesson about gravity

There’s a hole on the wall left behind by a removed picture frame, so I made a pinwheel for him to play with.

The popular IKEA’s Poang armchair helped my wife to rest during her pregnancy, but it fell out of use after the baby was born. The chair was dismantled and kept in the storeroom, but I had an idea for the frame. I turned it on its side, covered it with cardboard, gave it a flap, and we have a tunnel. It used to sit inside little one’s playpen as a house (and the fence becomes the garden), but now we just keep it at a corner, and take it out when some action is needed

The most enjoyable toys is made from the simplest things. I just took a carton box, cut out two doors, and wallah, we have a tunnel, a house and a place to play peek-a-boo

Of course, these are only the cool and successful ones. There are a lot of misses, and there are some that are not so cool. Making toys is a trial and error process—you’ll never know if he’ll like it. But the process of making is quite enjoyable too. And I already have some ideas in the pipeline for him.

As a parenting team, we’ve done a lot this year. But there are also things we had to keep aside. Our cooking adventure was reduced to special-occasions-only, and of course my food photography was completely halted (all my photography activity last year was to take pictures of the little one). My wife’s guzheng was left almost untouched (and ended up in the storeroom for most of the year). My drum set was my son’s toy, and my guitar was used mainly to play children’s songs for him. The number of movies we went to in the entire year can be counted with one hand (in fact, I just spent like an hour of my last moments being 29 to watch a bunch of trailers of movies that I have missed and will miss). We didn’t run or do much sports, except that we completed The Performance Series, having walked for more than half of the distances. To us, slipping away from the baby for a few hours so early in the morning, fighting off the thought to just skip the events, was already an achievement. So we are proud to show off our medal collection: 5 races, 50 km, 5 medals that merge to the map of Singapore.

I was once asked by a friend how I managed to do all this. Well, the simple answer is that I have an amazing supporting system. I have a wonderful wife who supports me enormously in everything I do. She is the main breadwinner for the family while I’m on student’s stipend. She has two new roles this year, both of which are tough, and she does them all while being a breastfeeding mom. We are an excellent parenting team because one of us would often have an idea and the other would carry it out. I also have two mothers who help to take care of the baby: one put aside her job to stay here with us, and one who’s always ready to fly here on short notice and on special occasions. I have a helper who loves the baby and whom I can trust. I have two brothers, and I have my whole huge family behind me. At school, I have a very supportive, kind, enlightening advisor, and I have a wonderful teacher-mentor-friend too. I’m surrounded by smart people and good friends who give me idea, cheer me up, and share meals and family stories with me.

Looking back, I’m quite happy to give myself a pat on the back. I worked really hard on my study, putting my best in every tasks. I tried hard to spend as much time with my son as I could, trying to understand him. My flexible time often makes me the only dad among moms and nannies at playgrounds. I can sense his poo-poo smell better than anyone else. I missed some of his milestones, but I was there when he first walked (and it was today, of any days!) I’m a happy husband, father, and student. I’m a happy 30-year-old. Happy birthday to me!

I’ve completed one year in my PhD program

So the third term of the year is over, which means I’ve completed my first year in the programme. The focus of the first term was on coursework, and the second term on research. This term is a balance between both, with an extra component: teaching assistant duty.The work load is heavy, and I worked really hard. The last two weeks of the term was the toughest, with all the due dates coming together. But that’s not only true for me, it’s also true for my students. As a result, I also received more questions from students during the last two weeks. Looking back, I’m actually quite amazed with myself that I pulled through.

It would have been a complete fairy tale if the term had actually ended with a high note and I had actually done well with everything. Of course, life is not perfect. I tripped at the last step and didn’t do well at the final for one class. I was very disappointed. I liked the class very much and I had been doing well. Somehow I wasn’t in the right state of mind during the exam. Probably my brain was too stretched out during the two weeks. But it’s okay. I’m happy with the semester. I’m particularly happy for two reasons:

  1. I found an excellent collaborator who clicks with me and who is as serious as me. I’m looking forward to more collaborations with him. We already have something in mind.
  2. A student came to me asking about a life decision: whether it’s better to work first or to continue straight away with his PhD. I must have done something right in class so that he trusted me with this question.

Now that the term is over, it’s family time. I’m gonna spend the next two weeks focusing on my family to compensate for the last two weeks. I’m gonna be back to being a cool daddy!

And then it’s back to research. I’ll spend 3 weeks of serious research before the term starts again.

I just met my advisor one last time before the term really ends today. He gave me a handshake with a very firm grasp and a pat on the shoulder. That says everything.

A milestone

Today is a high note at the very early of my career. I presented my summer project to faculty and students, and it was well received. It is a success. I am very happy that a faculty member recognized the efforts I put into preparing for the presentation apart from the research results. I am very excited about the work, and I wanted to make it exciting for other people.

It’s a pity that the joy was not successfully carried home. The dinner table and the evening was plagued by the worry of my son’s eating. But well, when you have a baby and you do your PhD, this is what you face.

New term

So the new term has started.

Tuesday was a day full of classes. Each of my 3 courses for this term has a session on Tuesday. And it is nice that the term started on a Tuesday, as I had a taste of everything on my very first day. And the taste was great. I certainly love learning (just a reaffirmation).

No class on Wednesday, but there was a welcome reception for all students, faculties and researchers. My team won the treasure hunt game. After the game, the faculties sat down, one at each table, and students can choose someone to talk to. I sat down with whom someone I really like really likes. And I could understand why. They are both bright and think along the same line. Here are some pieces of advice that I received:

  • Distinguish clearly working time and off time, so that you fully work during the working time and fully relax at the off time. It is better that you work with full concentration for 6 hours and play for the rest, than half-work for 8 hours and half-rest for the remaining time. Now, when I ask him how to do this with a baby, the second piece of advice came, which is a harder one to do.
  • With many commitments, it is hard to find a long block of time to work on a problem. But, it is quite likely that we have small chunks of time in between commitments. The art then lies in learning how to break your problems down to smaller chunks and solve each of them whenever you can. This is not the first time I hear this (I heard of this way back in NUS at a seminar), but it is time I learned to practice this.

Of course, certain tasks are not possible to break down, but requires full attention for a decent stretch of time. After reading this article on Science, I figured out that my solution would be to wake up at around 4 or 5 am and ave a good 2–3 hours working on my big problems. Certainly, this also depends on how my little one slept the previous night, but it is doable. I’ve done this 4 times over the past 10 days.

I also received good feedback on my writing skills—really appreciate that. What a good morale booster that was.

To the new term we roll.

Reflections: 3 months

The summer term is finally over. It ended on a high note with an A (and a spot in the top 3 of the class), and a summer project report that I am happy with. Overall, it was a successful term.

I did well in coursework. Three As in a row after the first two terms is a huge morale booster. Before this, I hadn’t had any serious study for almost 5 years. I feel that I have again a good momentum to continue rolling forward.

Anyways, research is more important, and that’s the main thing to reflect on. The focus of this third month was certainly the experiments. I did a lot of coding – I can do a lot more things in R now than I could before. I spent a lot of time trying to implement the PARMA model based on a couple of papers. It sort of worked, but not perfectly. As it turned out, it was not necessary for the paleoreconstruction experiment. Then I implemented a disaggregation algorithm and it worked nicely – easier than I thought it would be.

I think I need a better work flow – one that can integrate reading, writing and debugging code, running code for results, and writing everything down. Gotta try a few things.

The first semester was purely dedicated to coursework. The second semester focused a lot more on research. Next term, I’m taking two classes and doing TA for a half-semester course, which is actually a full course compressed into half. And I’m gonna continue to expand the summer project more. It’s gonna be a 3-way balancing act. I’ve learned to work with one and then two things at a time in the second semester. Third one is time for three. It’s just good timing. I can do it.

Reflections: 2 months

Two months into the first research project, it’s time to do a reflection.

My first semester was dedicated to coursework. I only did a few things on the side: read 3 papers, learned LaTeX, and kept a personal journal with a few entries (which is the predecessor for this blog). A great deal of effort was devoted to just getting used to studying again. Only until this summer did I start the actual research process.

At the beginning, I got to select among four topics. With a hunch and some exploratory readings, I chose climate variability based on paleo-reconstructed data. The remaining of the first month was spent reading the literature. Through some discussions with my advisor, I developed an interest in stochastic streamflow generation, which is a combination of the two courses that I learned in the first semester (Statistics and Stochastic Processes). This is of course a deviation from the original topic, but not a complete detour, because the two can be combined. At the turning point into the second month, I had an idea and presented it to my advisor. He thought it was good enough, and I proceeded. After some experiments, I realized that I was trying to do something novel without fully understanding the basics. So I kept that on hold and returned to building the foundation: time series analysis and ARMA model. Time-wise, I am now at the start of the third month, and progress-wise, I am at the level of reading textbooks and doing simple experiments.

Reading is hard. I am still struggling with digesting journal papers. I know it’s natural. The first few papers took me so much time – I would reckon a day each at least – because I had to stop at every other line to look up the concepts; everything was brand new, and I had to read them more than once. It is getting better now, as the more I understand, the less I need to look up. But there is still a significant number of mathematical equations to comprehend. The only way to get better is to keep reading. So, push.

I asked myself how I did back in my Bachelor’s and Master’s theses. Well, back then I was more or less told what to do, and I didn’t have as much going on in life as now.

I try my best not to blame the time working in the industry, but rather look at it in a more constructive way. During the past 4 years, as a way of adapting to the nature of the workplace, I had learn to be very practical and very broad. The experiences, especially those from the last year – the most difficult one, have trained me to think of constraints first whenever an idea comes about. I feel that I have become wiser in some sense, but I do need to change now. Doing a PhD is different – I need to think big, and I need to go very, very deep.

I haven’t read the book Mindset – the new psychology of success (by Prof. Carol Dweck), but I’ve read summaries and I know what it is about. Yet, I still have a fixed mindset when it comes to the weekly meeting with my advisor. I kept having this thought that I need to show him some results and prove that I can do research. He is very kind and supportive, so I know well that this is just from within me. Until this week. I had a chat with my wife and she helped me realize that I was being fix-mindsetted (I just made up this word; hopefully Prof. Dweck will approve), and that I am still learning. On the meeting day, I spent the whole bus ride to school clearing my head. As a result, I felt much better during the meeting. When it was over, I shared these thoughts with my advisor and he was very understanding.

Just one last anecdote. I’ve stopped reading PhD Comic. It was fun at first, but now I feel that it’s just too negative while I need to put my head in a more positive frame of thoughts.

What’s up for the next month? More reading and more coding, of course. Keep pushing.
