### To potential Ph.D students:

Note that unlike other professors who want to have a large research group,
I prefer a small to medium size research group with around four to five Ph.D students only.
This way, I can spend some quality time with my research students
to learn/think together, and to explore interesting research problems.
You may ask what are the * ''requirements'' * to be my Ph.D student.
Beside having a strong academic background in mathematics, algorithms and programming,
the most important criteria is that the student needs to be
* intellectually curious *. In other words, you need to have
a * ''passion in learning'' *.
If you think you are qualified, please send me email or come to my office
for discussion.

Currently, my group is working one two directions:
(1) Theory and applications of online learning (e.g., multi-armed bandit, reinforcement learning,..etc);
(2) Quantum algorithms and quantum Internet (which may use online learning algorithms).

For students who have a strong background in mathematics or theory,
for example, students who have degrees in Computer Science/Engineering,
Mathematics, Statistics and/or Physics,
our research group is actively seeking these candidates
on the above exciting research projects.
The backgrounds we seek, or the knowledge that you will learn in your Ph.D study, are:
* machine learning, probability, optimization, stochastic processes, statistical analysis
game theory, approximation algorithms, online learning, quantum computing,...etc.*

If you are interested, please send me an email.

### Quote

Last but not least, the following is a famous quote by Calvin Coolidge (1872),
whose statement reflects my research style and my expectation:

**
**

** Press on: Nothing in the world can take the place of persistence. **

** Talent will not; nothing is more common than unsuccessful men with talent. **

** Genius will not; unrewarded genius is almost a proverb. **

** Education will not; the world is full of educated derelicts.**

** Persistence and determination alone are omnipotent.
