Savyasachi is an astrophysicist, an instrumentation (radio frequency) expert, a data analysis / machine learning / AI / neuroscience enthusiast and a former poet. He has a PhD in Astrophysics from the University of Wisconsin-Madison (UW-Madison), where he received a Jansky Fellowship (2006-2007). Over the last decade, teaching has been a passion, as also mentoring and guiding school and undergraduate students. He has headed curriculum reform at IIT Indore. His teaching philosophy and practice is to get the students to be “hands-on”, so that the classroom and the lab are a single resource for students, and therefore should be integrated. In other words, the classroom MUST be a laboratory where students toy with explanations and stitch them together to understand, explore, and create, with the mentor / teacher guiding them along.
His current research focus is radio astronomy instrumentation and galaxy clusters, especially radio observations of cluster mergers. Based on their work on galaxy cluster mergers, Savyasachi and Abhi are leading a project on making India’s first radio observatory inside an institute / university. This project is funded by DST-SERB. With collaborators, he discovered the first non-thermal Sunyaev-Zeldovich effect at cm wavelengths, which is a step towards estimating the total energy budget of galaxy clusters, currently ill-constrained. This is one of the main aims of his research.
Currently upskilling in Machine Learning and AI, Savyasachi also dabbles in tinkering with small electronic equipment and now offers solutions for small electronics and communications needs, with collaborators.
The straitjacketed bio over, here's the reality. With a highly non-linear trajectory throughout his life, he is a lazy dreamer and tends to generally swim against any tide he finds himself in..ecumenically, grammatically, mathematically, physically and psychologically. He is a failure by any sensible standards, and a mad, bad egg - contact at your own risk.
In Isaac Asimov's Foundation universe, the motivation for psychohistory arose from the general idea of preserving humanity. Ironically, this idea was formulated by two robots - R. Daneel Olivaw and R. Giskard Reventlov as the Zeroth Law of Robotics.
R. Daneel Olivaw lives on and lays the foundation of the Galactic Empire, and assumes two identities in the reign of Cleon I:
- Eto Demerzel, the Emperor's trusted Minister
- Chetter Hummin, a mischievous reporter who inspires and pushes Hari Seldon to formulate psychohistory as a science. His name is a play on the words cheater and human. So, his name can be interpreted in a myriad of ways. The way I choose to interpret it is as follows. R. Daneel Olivaw cheats the death of human civilization through his invention of psychohistory. He is therefore the most compassionate of humans...hence the name of this website.
