Random Walks

By Abhigyan Ray
The process of science as a whole seems an interesting but daunting prospect. To explore the intricacies of science, join me for ~60 minutes each week as I indulge in a freewheeling conversation on science and myriad other things with an eclectic set of professors, graduate students, physician-scientists, journal editors, science communicators, ethicists, and anybody who does science! In our Random Walks, we delve deep into the numerous challenges doing science entails and how everyone charts a unique collaborative path through it. linktr.ee/randomwalks
