I am assistant professor at the department of Computer Science at UNH with a focus on text-based machine learning and information retrieval as well as data science on watersheds.
Previously I was a Post-doctoral Research Scientist at the Data and Web Science Group of Mannheim University, working with Prof. Simone Paolo Ponzetto. Before that I was a Research Scientist at the Center for Intelligent Information Retrieval (CIIR) working with Bruce Croft at University of Massachusetts. Before that I did a post-doc with Andrew McCallum. I graduated from Max Planck Insititute for Informatics in Saarbruecken, Germany in January 2011.
See teaching page for more information about my courses offered at UNH
Fall Semester (every odd year, e.g. 2019):– the course was listed as CS 780/880 in Fall 2016.
Fall Semester (every even year, e.g. 2020): – the course was listed as CS 780/880 “Machine Learning for Sequences” in Fall 2020.
Spring Semester (annually): (implementation-intensive) – the course was listed as CS 980.02 in Spring 2017.
Spring Semester (annually): (theory-intensive) – the course will be taught in Fall semesters by a different instructor.
I also offer thesis/projects.
Anyone can attend my lab meetings.
I also taught several lectures on natural language processing and knowledge graphs for information retrieval at conference tutorials and summer schools.

My research, mentoring, and teaching, and external service activities evolve around the following areas of interest.
Information Retrieval, Knowledge Graphs, and Natural Language processing. This area is related to my CAREER grant, TREC CAR competition, and the vision to automatically creating Wikipedia-like comprehensive articles for given topics.
Environmental data science for temporal sensor streams, in order to offer a better understanding of solute transport in watersheds for hydrologists and biogeochemists.
Please see research project page for details.
Shubham Chatterjee. Shubham is working on Entity ranking and Entity-support passage retrieval with entity representations and entity aspects. (Graduated with a PhD 2022, looking for a Post-doc!)
Sumanta Kashyapi. Sumanta is working on topic extraction for complex answer retrieval. (Graduated with a PhD in 2022; now working for Dell)
Satanu Ghosh. Satanu is working on generating suggested questions and answers for conversational search.

The vision of HIPstIR is that early stage information retrieval (IR) researchers get togetherto develop a future for non-mainstream ideas and research agendas inIR. Important priorresearch can be discussed in the form of reading groups. A future vision of what IR can (orshould) be—and how to get there—must be developed. It is like SWIRL (Moffat et al., 2005,Allan et al., 2012, Culpepper et al., 2018) in spirit but focusing ontopics that may otherwisebe considered “niche”, “alternative”, “indie”, or “left field”. An explicit goal of this workshop isto foment collaboration and cross-group fertilization. The hopeis that participation will giverise to conference workshop topics and joint paper projects. Primaryfocus is on early stageresearchers that are anywhere between defending their PhD within one year to one year intobeing a tenured professor or a senior scientist, but few senior people may also be invited
We hope more folks will branch off and organize HIPstIR’s all over the place. HIPstIR is public domain / CC0.
