Prof. Cha’s Biography

Sang Kyun Cha is a professor and an entrepreneur. He worked on three generations of commercialized in-memory database platforms since he joined Seoul National University in 1992. In 2000, with his vision of the coming era of in-memory enterprise database, he founded Transact In Memory, Inc., and started developing his second-generation system P*TIME (Parallel* Transact-In-Memory Engine). The company was quietly acquired by SAP in November 2005 and transformed to SAP Labs Korea.

By early 2006, P*TIME development was complete with an innovative in-memory OLTP architecture: parallel logging and recovery, in-memory-optimized MVCC, and optimistic latch-free index concurrency control. To demonstrate its extreme OLTP scalability in tight integration with SAP’s middleware and application stacks, P*TIME also implemented a seamless two-tier interface resilient to application crash in addition to three-tier interface.

With SAP’s column store TREX, P*TIME became a corner stone of building SAP HANA, the first transactional distributed in-memory enterprise database platform which became generally available in June 2011. Today, SAP and numerous companies run ERP, CRM, and real-time analytics on HANA. By SAP’s request, Prof. Cha took the co-responsibility of developing HANA with German colleagues and saw its world-wide adoption.

With his experience, in April 2014, he launched Seoul National University’s Big Data Institute to respond to trans-disciplinary big data research interest of both computer scientists and domain experts from various academic disciplines such as engineering, natural and social sciences, and medicine.

Prof. Cha is a board member of Seoul National University. He has also been a board member of Korea Telecom since March 2012, and is providing strategic advice to central and local governments on big data and software industry issues. In 2015, as the General Co-Chair, he led the IEEE ICDE 2015 Conference in Seoul, Korea to become the most successful ICDE in the past decade, attracting participant numbers doubling previous years. He was elected as the steering committee member of IEEE ICDE. He is also on the editorial board of the VLDB Journal since 2009. Prof. Cha received his BS and MS from Seoul National University and his Ph.D. from Stanford University.

Prof. Krishnan’s Biography

Ramayya Krishnan is the W. W. Cooper and Ruth F. Cooper Professor of Management Science and Information Systems at the H. John Heinz III College and the Department of Engineering and Public Policy at Carnegie Mellon University. A faculty member at CMU since 1988, Krishnan was appointed Dean when the Heinz College was created in 2008. He was reappointed upon the completion of his first term as Dean in 2014.

Krishnan was educated at the Indian Institute of Technology and the University of Texas at Austin. He has a Bachelor’s degree in mechanical engineering, a Master’s degree in industrial engineering and operations research, and a PhD in Management Science and Information Systems. Krishnan’s research interests focus on consumer and social behavior in digitally instrumented environments. His work has addressed technical, policy and business problems that arise in these contexts and he has published extensively on these topics. He has served as Department Editor for Information Systems at Management Science, the premier journal of the Operations Research and Management Science Community. Krishnan is an INFORMS Fellow, a member of the Global Agenda Council on Data Driven Development of the World Economic Forum, and a former President of the INFORMS Information Systems Society and the INFORMS Computing Society. He is the recipient of the prestigious Y. Nayuduamma award in 2015 for his contributions to telecommunications management and business technology.

Krishnan’s leadership experience include the founding of the information systems and management program at Carnegie Mellon, and his term as the First Dean of the Heinz College, a unique college that is home to both the Public Policy School and Information Systems School at Carnegie Mellon. This unique co-location of information technology, public policy and management brings together a multi-disciplinary faculty consisting of engineers, social scientists and information technologists dedicated to educating “men and women of intelligent action.” Faculty and students address important issues at the nexus of information technology, policy and management that arise in domains such as information privacy, evidence-based health care delivery, and urban consumer behavior. The College’s global footprint in the US (Pittsburgh and Washington D.C.), in Singapore and in Adelaide, Australia enable these issues to be addressed from a global point of view using international testbeds and via bi-continental educational programs.

Krishnan led the establishment of research centers focused on data driven decision making in key societal domains including transportation (http://traffic21.heinz.cmu.edu/), smart cities (http://www.ices.cmu.edu/metro21/), and living analytics (http://larc.heinz.cmu.edu) and risk and regulatory innovation (https://www.cmu.edu/risk-reg-center/). He has participated in the World Economic Forum and a summary of his ideaslab presentation is at http://goo.gl/IqkMKR. A recent interview on Big Data with NDTV is at http://goo.gl/WyxEi3.
