Currently interested in Schur functions and semistandard Young tableaux and misc. related representation theory and combinatorics.

Phd thesis defended 2013, titled Combinatorial Methods in Complex Analysis.

I keep an eye out for interesting results related to complex dynamics, computability, and computer-assisted research. I use Mathematica extensively in my research. My other main programming languages are Java, LaTeX, PHP, C, etc.

comment Video game addiction
25h/w, is perhaps 3h/day. Say, if he worked out 2h/day, and watched tv 1h/day, you would not react at all, I think, but rather think this is normal, borderline healthy. Besides, a high class load, also requires some time to distance from school stuff. I think that I also had similar statistics on gameplay in those years, at least for some periods.

He is not color-blind, perhaps?

comment Teens concerned about impregnation through clothes
Hence, inform about condoms, and why one should always carry (a fresh one) with you.

comment What should I do about my pre-teen son messaging older girls he's never met?
I am curious, what did you say about porn?

comment Helping a child independently make logical connections
Computer games. There are a lot of computer games where you need to do several steps of thinking; for example "Flow", html5games.com/2012/07/flow-free

comment What is the least problematic age difference between siblings?
I just want to share my experience: I have (much) more in common with my youngest sibling (my brother, 10 years younger), than any of my four sisters which are between us.

comment How to handle a 11y/o son who act like a girl?
"He plays mostly with girls at school". Why do you object to this? Maybe it is because he likes girls?

comment How do you determine when to start a child on music lessons without pressuring them?
Pressuring is really a balance I think; I felt some pressure with continuing my instrument, but I am happy that my parents were persistent. Learning to give up at the first hurdle is not a good lesson.

comment What are some milestones a child should reach before learning programming?
Learning how to read music sheets is very similar to learn how to read code.

comment What are some milestones a child should reach before learning programming?
I learned to code on a Ti-83 calculator, since my parents limited my PC usage to 1h/day, so I did not want to waste "gaming time".

comment The school has assigned reading I feel is inappropriate for my son to read. How do I approach this problem with the school and with my son?
The best way to make the kid to read a book is to forbid him/her doing so. My parents did not allow me to watch Stephen King movies when I was 11 (obviously), but they did not mind me reading the novels, which I did. I think this was a very good way for me to become interested in reading, and I still read a lot of books. Besides, you can always easily pause a book, and experience in your own pace. There is no harm in reading this series I think.

comment How do you teach a child religious views?
The bible is also very clear that you should not eat shellfish, (Leviticus 11:12).

comment Somewhat unemotional, destructive pre-schooler; shows no strong attachment to things. How can we help him?
I say, encourage the curiosity. How about finding some old electronic devices and a screwdriver for him to play with. Taking apart electronics is really funny, (lots of colors and strange things). Just be careful that he do not plug them into an outlet again!

comment How does one address Christianity with their children in a mixed faith marriage?
How about wait until your child is old enough to understand the stories in the Bible, and discovering faith on her own. It is very easy to misunderstand faith and religion on an early age, and some stories in the Bible are really not appropriate for people under 18...
