Sean T. successfully defended his Ph.D. dissertation "Revealing Ultrafast Dynamics and Functional Basis of Potential Biomedical Tools from Calcium Sensing to Optogenetics" via Zoom earlier today (July 14, 2021). Now from our group since Sep. 2010 at OSU, we have had Drs. Han, Oscar, Wang, Tang, Zhu, Chen, and Tachibana (7) as of July 2021. 

Congrats, Dr. Tachibana! Best wishes for your future work, with a productive and enjoyable scientific/research/development career ahead! Keep us posted.
