Welcome @skyrudrapratap 
Sorry I couldnt get to your questions at the office hours this AM 
Analog mission command plus physiotherapy training is a good combination for the astronaut health side of AWG activity R&D.
Your best fit is the new Spaceflight Epidemiology AWG. Reach out to @robert.j.reynolds-2 and @holquistkl to get involved and introduce yourself at the next monthly meeting. @Matthew_Murphy can also answer questions about the group and its projects.
While you get oriented, spend time in the data:
Data dashboard (at a glance): NASA OSDR Biological Data and Visualization Portal
Search portal: NASA OSDR: Open Science for Life in Space
Previous work: NASA OSDR-GeneLab Enabled Publications, Pre-Prints, Student Theses - Google Scholar
All quick links to data/tools/APIs, etc are here: About - Open Science Data Repository Analysis Working Groups
Pick a project from the master table and find the meeting on the calendar (log in first).
Cheers,
-Ryan
