| Dr. C. Mohan joined
the Computer
Science Department of the IBM Almaden
Research Center as a Research Staff Member in 1981 where he has worked
on a number of topics in the areas of database,
workflow and transaction management. From June 2006 until
January 2009, he worked as the IBM India Chief
Scientist, based in Bangalore,
with responsibilities that relate to serving as the executive technical
leader of IBM India within and outside IBM. In 1997, Mohan was named to IBM's highest technical
position of an IBM Fellow for
being recognized worldwide as a leading innovator in
transaction management. In 2009, he was elected to the US
National
Academy of Engineering (NAE) and the Indian National Academy
of Engineering (INAE). He received the ACM
SIGMOD Innovations
Award in 1996 in recognition of his innovative
contributions to the development and use of database
systems. At the 1999
International Conference on Very Large Data Bases,
he was honored with the 10
Year Best Paper Award for the impact of his work on
the ARIES
family of algorithms. In 2002, he was named an ACM Fellow and an IEEE Fellow. In 1992, he was elected a
member of the IBM Academy of
Technology. Currently,
he is a Council member of IBM's Software Group
Architecture Board, and a member of Academy of
Technology and Information
Management Architecture Board. In the past, he has been a member
of IBM's Technical Leadership Team (TLT), IBM's Research Management
Council (RMC), IBM India's Senior Leadership
Team, the IBM Asset Architecture Board, and the
Bharti Technical Advisory Councils. He is also on
the Academic Senate of the International Institute of
Information Technology (IIIT) at Bangalore.
In late 1996,
Mohan founded and started leading the Dominotes
project whose goal was to enhance Lotus Domino/Notes's
scalability and fault tolerance by introducing
transactional recovery in Domino R5. Earlier, Mohan led
the Exotica
project which was focused on advanced transaction
management and on IBM's workflow product FlowMark
(now called MQSeries Workflow), messaging product MQSeries
and groupware product Lotus Notes. During 1998-99, he was
on a sabbatical at INRIA, Rocquencourt
(France). Mohan was a designer and/or an implementer of the R*
distributed DBMS, the Starburst
extensible DBMS and DB2.
He is the primary inventor of the ARIES family of
recovery and concurrency control methods, and the
Presumed Abort commit protocol. He has lectured
extensively, and authored numerous conference
and journal papers on concurrency control, recovery,
commit protocols, index management, query optimization,
active databases, architectural support for transaction
processing, parallelism, OODBMSs, client-server computing,
remote-site backup, caching, workflow, data sharing and
distributed systems. He is a consultant for numerous IBM database, transaction
processing and workflow
product groups. His research ideas have been incorporated
in the IBM products DB2/390, DB2 for
Unix, Windows and OS/2, DB2
Server for VSE & VM (the former SQL/DS), IMS,
MQSeries,
S/390 Parallel Sysplex
Coupling Facility, WebSphere, Cloudscape, Lotus Notes/Domino, VM Shared File
System, AdStar Distributed Storage Manager (ADSM,
now called Tivoli Storage Manager)
and Workstation Data Save Facility (WDSF/VM), in the IBM
prototypes R*, Starburst and QuickSilver, in IBM's
SNA LU6.2 and DRDA
architectures, and in Microsoft SQLServer, Sybase and Informix.
Mohan is the recipient of several
IBM awards: an IBM
Corporate Award for database support for parallel sysplex; another
Corporate Award for his invention of the ARIES
recovery method which is being used extensively in several IBM
products, in Transarc's Encina
Product Suite, and in the University of Wisconsin's Gamma
and EXODUS
DBMSs, and SHORE
persistent object system; an IBM Outstanding Innovation Award
(OIA) for ARIES; an OIA for his inventions (ARIES,
ARIES/IM, Commit_LSN) and major contributions to
performance, availability and concurrency in DB2/MVS V4;
three OIAs for his algorithmic and hardware architectural
coinventions for supporting the shared disks transaction
environment in S/390 and DB2/MVS; an Outstanding
Technical Achievement Award (OTAA) for enhancements to
Lotus Domino to provide log-based recovery; an OIA for
his coinvention of the Hybrid Join method which is
implemented in DB2/MVS; an OIA for his coinvention of the
Presumed Abort commit protocol which has been widely
adopted in the industry and which is now part of the ISO-OSI, X/Open and DRDA
distributed transaction processing standards; an IBM Research Division
Award (RDA) for his work on transaction management in R*;
an RDA for his contributions to WDSF/VM (now called TSM); an RDA for his
contributions to WebSphere Messaging; 10th Plateau IBM
Invention Achievement Award for his patenting activities (34
issued patents). Mohan was named a
leading inventor of IBM for 1994 and 1995, and a Master
Inventor in 1997.
Mohan was the Americas Program Chair for the 1996
International Conference on Very Large Data Bases,
the Program Chair for the 1987
International Workshop on High Performance Transaction
Systems and a Program Vice-Chair for the 1994
International Conference on Data Engineering. He was the Industrial Program
Chair for the 2003
International Conference on Data Engineering. He has
been on the program committees of the conferences SIGMOD,
PODS,
ICDE,
ICDCS,
VLDB,
PDIS,
HPTS,
COMAD,
ADB
and Compcon.
He
has been on the advisory board of IEEE Spectrum, and an editor of the VLDB
Journal and Distributed
and Parallel Databases - An International Journal. He
was an Associate Editor of IEEE's Data Engineering
Bulletin. He has been a visiting scientist in Hahn-Meitner-Institut
(Germany). Mohan received a PhD in Computer Science from
the University of
Texas at Austin in 1981. In 2003, he was named a Distinguished
Alumnus of IIT
Madras from which he received a B.Tech. in Chemical
Engineering in 1977. He is a frequent speaker in North America,
Western Europe and India, and has given talks in 35 countries. More
