Algorithms and Data Structures

Faculty : Dr. Raghunath Tewari, Dr. Ratan K Ghosh, Dr. Sanjeev Saxena, Dr. Shashank Mehta, Dr. Sumit Ganguly, Dr. Surender Baswana

We are a group of faculty and students working on exciting problems on the recently very popular areas in algorithms and data structures including dynamic graph algorithms, fault tolerance, streaming algorithms, computational geometry, graph theory and space bounded algorithms. We are interested primarily in the research problems and general directions given below, but are also adaptable and receptive to new interesting problems that may come up in the near future.


Faculty : Dr. Phalguni Gupta

Biometrics lab at IIT Kanpur is actively involved in the development of biometric based authentication systems that can handle multiple traits such as a face, fingerprint, palmprint, iris, ear, knuckleprint, hand geometry, hand vain, finger vein, signature etc. The idea is to use the physiological or behavioral characteristics of a person to identify him in an automated way. This lab also provides consultancy to various government agencies on these matters.

Compilers, Programming Languages and Analysis

Faculty : Dr. Amey Karkare , Dr. Subhajit Roy

The department has a focused interest on the theory and applications of programming languages and program analysis. The main research areas are compilers, data flow analysis, heap analysis, formal techniques for automated debugging, program verification and synthesis, program profiling, compiler optimizations, GPU algorithms. Of particular interest is a recent project being executed by Prof. Amey Karkare, Prof. Subhajit Roy and Dr. Sumit Gulwani (adjunct faculty, MSR Redmond) on developing intelligent tutoring systems [link] that are designed to adaptively guide students who are learning programming or other tools and tasks for the first time. The project has been successfully piloted with the introductory programming course at IIT Kanpur which graduates more than 800 students each year.

Computer Architecture and Operating Systems

Faculty : Dr. Biswabandan Panda, Dr. Debadatta Mishra, Dr. Mainak Chaudhuri, Dr. Rajat Moona

As Moore's law is almost near to its death, the only way to improve microprocessor performance is by designing and optimizing better architecture. Work on this domain is mainly exploring possibilities to break classical problems in micro-architecture like memory wall.

Currently the group focuses on designing memory systems for emerging application domains that are resilient to application behavior. The group also focuses on the interface between Operating Systems, Architecture, and Virtualization techniques.

Cyber-Physical Systems

Faculty : Dr. Indranil Saha , Dr. Sandeep Shukla

In this age of automation, usage of complex safety-critical systems are increasingly high in industries like hardware, automobiles, avionics, space etc. This is a major task to ensure correctness and completeness to get a reliable controller of such systems. The CPS Group at the CSE Department of IIT Kanpur is working on developing principled approaches for robust implementation of cyber-physical systems. A cyber-physical system is a collection of interconnected computing devices interacting with the physical world to regulate its behavior. The group is working on several exciting problems in the area of CPS, more specifically in distributed multi-robot systems and internet-of-things. The focus of this group is to develop cyber-physical systems with correctness guarantee through the application of formal verification/synthesis techniques.

Cyber Security / System Security

Faculty : Dr. Biswabandan Panda, Dr. Manindra Agrawal, Dr. Rajat Moona, Dr. Sandeep Shukla

With terrorist organizations (e.g. ISIS), and other adversaries abound, Cyber-Security is not just a computer science issue but a national security issue. National critical infrastructures are ripe targets for cyber-attacks. At IIT Kanpur, leveraging the expertise in multiple areas of Computer Science and Engineering we initiated such a comprehensive program within our center for cyber-security. We have a multi-disciplinary national project to carry out research, training and education in cyber security of the national cyber space including information infrastructure, and other critical infrastructures such as banking, power grid, industrial manufacturing, defense tactical communication networks, and various information assets of the country.

Our approach is multi-pronged and multi-layer -- defense-in-depth strategy. Starting from crypto algorithms and protocols, side-channel proof crypto engineering to vulnerability analysis of systems and application layer software, network and web security, cloud security through virtual machine hardening, and use of machine learning for anomaly detection to fight persistent threats in the critical infrastructure.

Several cyber security research groups from IIT Bombay, IIT Kharagpur, ISI Kolkata, IIIT-Delhi, and MNIT, Jaipur have agreed to associate their research groups/centers with the proposed center. Exchanging faculty and study for short and long periods for collaborative research and pursuing problem specific funding together will be the modality of these associations. As a show case of the center's productivity, three specific problem areas have been identified -- solutions of which are being pursued and show cased to the highest levels of the government.

The group also focuses on Side-channel and Covert-channel attacks through the processor, caches, and memory system.

Databases, Big Data and Data Mining

Faculty : Dr. Arnab Bhattacharya , Dr. Medha Atre, Dr. Sumit Ganguly

Databases are ubiquitous and form the backbones of almost all the modern systems. While traditional databases are relational, the NoSQL paradigm has proved itself useful in various applications and situations, especially in the realm of big data. The research in this field encompasses data analytics, data processing, indexing, querying, searching and information retrieval. It also includes data mining in the form of graphs, text, multimedia, strings, etc.

With proliferation of data emerging from heterogeneous sources, data analytics is being considered as the key tool for business growth, and understanding the physical world. While there are already many tools for analyzing structured data, there are still many open problems for unstructed or semi-structured data, speech, and video data. The Big data phenomena encompasses all of these, and is thus the buzz word of this era.

Machine Learning and Computer Vision

Faculty : Dr. Harish Karnick, Dr. Nisheeth Srivastava, Dr. Piyush Rai, Dr. Purushottam Kar, Dr. Vinay P. Namboodiri

This is an area where the department has had a recent surge in terms of strength, as well as diversity. We cover nearly all the challenging areas of machine learning and computer vision. In ML, it focuses on theoretical probabilistic machine learning, deep learning, optimisation, natural language processing etc. In vision, it mostly works on language and facial analysis, graphics, human attributes prediction, pose estimation, action/activity prediction, human-centered computing, human factors in computing, Computational Cognitive Science etc.

It boasts of publications in ICML, NIPS, AAAI, IJCAI, AISTATS etc. The department has an active reading group in machine learning called SIGML which regularly hosts invited talks and guest lectures.

Software Architecture

Faculty: Dr. T. V. Prabhakar

In the era of Internet-scale applications, the success of a software application greatly depends on its quality attributes such as performance and scalability. To ensure the quality attributes desired by an application, the architect has to design a suitable architecture -- which is a very complex task. The contemporary computing platforms such as mobile and cloud alleviate the problem due to the partitioning of quality concerns and architectural implications of the characteristics of these platforms. Software architecture community tries to abstract out the experiential knowledge from various domains and presents tools to design architectures such as tactics, reference architectures, and frameworks.

Theoretical Computer Science

Faculty : Dr. Anil Seth, Dr. Manindra Agrawal, Dr. Nitin Saxena, Dr. Piyush Kurur, Dr. Raghunath Tewari, Dr. Rajat Mittal, Dr. Satyadev Nandakumar, Dr. Somnath Biswas, Dr. Sumit Ganguly, Dr. Sunil Simon
