Jana left the Pakrasi Lab in January 2013 to take a new position at a company that I will find the name of and put here.

Research Interest:

I am interested in understanding the complex cellular interactions of unicellular photoautotroph’s that facilitate adaptation to changes in their environment.  My current studies focus on the impact of high CO2 concentrations on the metabolism of diazotrophic and non-diazotrophic cyanobacteria.
