Srinivasan Keshav is the Robert Sansom Professor of Computer Science in the Department of Computer Science and Technology at the University of Cambridge and a Fellow of Fitzwilliam College. Previously, he was a Professor at the David R. Cheriton School of Computer Science.

Although he started out as a researcher in computer networking in 1988, since 2010 his focus has been on reducing the carbon footprint of energy generation, transportation, and buildings. For the past couple of years, he also worked on improving the performance of the Hyperledger Fabric blockchain so that it can be used as the foundation for highly-scalable energy systems, such as for transactive energy and renewable energy certificates. 

He has recently turned his attention to the carbon sequestration and biodiversity potential of forests, looking at both conservation and restoration.

Shane McIntosh joined the Cheriton School of Computer Science as an Associate Professor in July 2020. 

His research area is in empirical software engineering. More specifically, he has focused his research on release engineering. He has made significant research contributions in intelligent release pipelines, code review analysis, and mining software repositories. As of October 2019, Professor McIntosh has published 16 journal papers and 32 conference papers, all in the top research venues and leading journals of the field. As of August 2021, his papers have been cited more than 3,800 times with an h-index from Google Scholar of 32. He has been invited to many international workshops, such as Shonan and Dagstuhl.

Professor McIntosh has also contributed to the software engineering community as a program committee member in several top conferences, such as ICSE, FSE, and OOPSLA. He has been the co-chair of multiple workshops on release engineering and the co-chair of several tracks in top tier conferences. He was awarded a Canada Research Chair (Tier II) at McGill, and he was a Vanier Canada Graduate Scholarship holder. He was one of two Ph.D. graduates from the Queen’s University class of 2015 to be recognized with the Academic Gold Medal from Governor General of Canada for his Ph.D. work.
