DESCRIPTION:Anupam Sengupta\, University of Luxembourg\n\nfor the The Parso
 ns Lab Microbial Systems Seminar Series @MIT\n\nAbstract: The ability of m
 icrobes to rapidly respond to environmental cues\, spanning vastly differe
 nt time and length scales\, is a conundrum that has long intrigued biologi
 sts and physicists alike. In this talk I will focus on one of the key cell
 ular traits – adaptation – and ask how this emerges in motile phytopla
 nkton due to a universal environmental parameter: hydrodynamic fluctuation
 s. Using bloom forming species as model microbes\, I will present recent r
 esults that show how phytoplankton can rapidly trait-shift in response to 
 fluctuations in their hydrodynamic environment. We uncover that phytoplank
 ton can actively diversify their phenotypic traits [1]\, and that this eme
 rgent behavioral switch is underpinned by generation of physiological stre
 ss. Intriguingly\, the dynamics of stress generation and dissipation are c
 oupled to the structure and duration of the imposed fluctuating field [2].
  I will discuss our ongoing efforts to uncover the physiological ramificat
 ions of the fluctuating cues\, both over short and longer timescales relat
 ive to the division times. I will conclude by highlighting the generality 
 of our results across phytoplankton species\, and why our efforts to decod
 e the principles governing fluctuation induced emergent functions are crit
 ical in deciphering fitness and community landscapes\, more so during the 
 rapidly shifting patterns that we encounter in our environment today.\n\n\
