Really Personal

• Can communicate in German, in English and certainly also in

Chinese.

• Could be a little overexcited among new friends in new

St. John's College! We will have an amazing time together!"

Personal Answers to Professor Dan's Questions

What are your main interests?

• Topics in evolutionary biology especially the origin of sex, the

maintenance of sex and also the theory of life history.

• Mathematical modelling of population dynamics under

ecological considerations.

• Structure and dynamics of social networks.

What sort of expertise can you bring to the group?

Statistics, nonlinear dynamics and computer simulation with

C++.

What do you hope to get out of the CSSS?

• Broad overview and outlook of complex systems researches.
• Alternatives of computational techniques and methods.
• Experience of intercultual teamwork

Besides, I have been wondering if there is a hope to crack

sufficient genetic codes to offer the processe of human evolution a

good statistic. I hope I could figure the answer out. ====Do you have any possible projects in mind for the CSSS?

==

Yes. In the context of bacterial transformation, it may be

interested to estimate the critical virulence of a virus from which

the virus can drive a bacterial population til extinction, in

consideration of the initial population size of bacteria and

nutritional limitation.
