My research is on distributed and scalable data platforms to support Big Data and Internet of Things (IoT) applications on novel computing infrastructure, such as Clouds and Edge devices. I lead the DREAM:Lab - Distributed Research on Emerging Applications and Machines - at CDS. Details of various research activities of the lab is available at the lab webpage


A new course on DS256: Scalable Systems for Data Science (3:1) is being offered in the Jan semester starting from 2016 at the CDS department. The course covers platforms and tools required for developing algorithms, and programming and analyzing Big Data. A programming project is an essential part of the course, with students working over real-world, large datasets, and using Big Data platforms at scale.

The SE252: Introduction to Cloud Computing (3:1) is occasionally offered as an elective course in the Aug semester. The course covers topics on parallel and distributed computing; IaaS/PaaS/SaaS Clouds; Big Data processing patterns on Clouds; Runtime execution models on Clouds; and Performance evaluation of Cloud applications.

I co-teach DS221: Introduction to Scalable Systems (3:0), which is a new core course that blends various systems concepts for students new to data science and those without a formal Computer Science under-graduate degree.

Earlier, I taught the DS286: Data Structures and Programming (2:1) core course in the Aug semester, sometimes with Prof. Venkatesh Babu. I also co-taught the SE292: High Performance Computing (3:0) core course in the Aug 2014 semester, along with Prof. Govindarajan. Both of these have been discontinued, and topics absorbed into DS221.

Prospective Students & Projects

Applied systems research requires hands-on programming skills to validate research ideas. Students interested in working with my lab should have demonstrated experience with programming and algorithms, preferably in Java, through online coding contest and Hackathons, such as CodeChef, SPOJ, HackerEarth, etc. Knowledge of Big Data platforms like Hadoop/Spark/Storm, Cloud fabrics like OpenStack and experience with Open Source projects will help too.

I welcome Ph.D. and M.Sc. research students at CDS interested in working with me. You are encouraged to view the lab's research activities, review relevant literature and our recent papers, and contact me with specific research areas and problems that you are passionate about.

Projects on state-of-the-art topics on Big Data and Cloud+Edge systems are available for M.Tech. by coursework students. These projects will place an emphasis on innovative research ideas as well as practical grounding through software prototyping and benchmarking on Cloud and distributed clusters. Students will be expected to publish a research paper as a project outcome. Sample projects topics are available from our lab's webpage. If you are interested, send me an email to schedule a meeting by Dec/Jan. Students must take the SE252:Introduction to Cloud Computing Course or SE256:Scalable Systems for Data Science Course as a pre-requisite.

Limited undergraduate summer internships are available to highly motivated students interested in pursuing research as part of their final year project. Students must be able to spend a semester in addition to summer (9-12 months) at IISc. Applications are open on a rolling basis starting the December before the internship term (e.g. Dec 2014 for May-Dec 2015).

Research associate and project staff positions are available in the area of Cloud Computing, Big Data platforms and Internet of Things. The position is for a minimum of 1 year, and offers a chance to work on research projects, collaborate with students, and publish research papers. Applicants should have a Masters' or Ph.D. degree in Computer Science; in exceptional cases, those with just a B.E. or B.Tech. degree in Computer Science will be considered. Demonstrated programming experience, through work on large open source projects, coding challenges (Googe SOCC, CodeChef) or hackathons, is required.

Students interested in applying to IISc should review the admission guidelines for IISc and CDS. IISc offers a world-class research environment, is consistently ranked the best research university in India, by Times Higher Education, ARWU and QS World University Rankings. CDS offers a unique 2-year M.Tech.(Computational and Data Science) program by coursework and project, in addition to research degrees of M.Tech.(Research) and Ph.D. Research students interested in working with me should select the Computer Systems Stream (CDS-CS) and prepare for the interview topics for the DREAM:Lab, as listed in the research admissions brochure. The admission process is highly competitive and requires a GATE exam score for those with a Bachelors' degree, besides onsite interviews.
