Sabyasachi Sarkar

  • Assistant Teaching Professor, Physics

Professor Sabyasachi Sarkar is a former Marie Curie Fellow who joined the WPI faculty in 2011 and has since been serving the Physics department as an adjunct professor. Professor Sarkar’s research interests lie in biological materials. Since 2007, he has been passionately striving to understand how materials interact with broad ranges of the electromagnetic spectrum and how we can interpret and manipulate our perceptions of this interaction.

The most apparent applications of such understanding in engineering and the sciences are in sensor technology. With more than 80 percent of the U.S. adult population having had contact with a health care professional in the past year (according to the CDC’s published 2012 Summary Health Statistics for US Adults) sensor importance in the health care sector can never be overemphasized. In 2008 alone, there were approximately 1.2 billion visits to physician offices, as well as hospital outpatient and emergency departments.

Professor Sarkar’s approach to sensor development follows a two-pronged approach, the first being a systematic bottom-up material fabrication and material property determination via analytical tools like ellipsometry. The second route follows a detailed theoretical approach to sensor development via material property-based modeling and simulation.

Professor Sarkar is also very devoted to understanding and educating people about the fundamentals and figuring out what makes things tick. It is no surprise that he joined WPI, where he gets ample scope to fulfill two of his central cravings. Teaching, he says, is very rewarding to him personally, as he not only gets to inspire and shape young engineers and scientists but also gets to see how they evolve through their years at WPI. He loves to interact with his students and insists that the interactions are the best part of the pedagogical process, as even he secretly gets to learn more. These fruitful interactions are possible thanks to the highly motivated, diverse, and engaged student body at WPI.

Most people who know Professor Sarkar address him as “Saby” and know his love of travel, food, and feeding people.
