Sushovan De :: Home

Welcome to my corner on the internet. My name is Sushovan De (that's pronounced [suːʃoʊvən ðɛ], and written as সুশোভন দে in Bangla).

I am currently employed at Google. I graduated with a Ph.D. from Arizona State University (ASU), in the CIDSE department. My research focused on Information Retrieval, Data Cleaning, and Probabilistic Databases.

I write code as a hobby, check out my projects from my various coding pages. I also tinker with photoshop from time to time, check out my wallpapers and website designs.

My Résumé

You can download my résumé in word, pdf or plain text formats.


2008 - 2014: PhD in Computer Science, advisor: Dr. Subbarao Kambhampati,
Arizona State University; GPA 4.00/4.00

2003 - 2007: Bachelor of Technology in Electronics and ECE,
Indian Institute of Technology, Kharagpur; CGPA 8.27/10

Areas of interest, current projects:

Information Retrieval: Built an end-to-end system that does unsupervised data cleaning on both offline and autonomous databases. Used Bayesian networks to model the data, and used error model to find the best correction. Implemented a novel query rewriting scheme to efficiently get results from autonomous / web databases. New: You can now try the system yourself: BayesWipe Database Cleaner now allows you to clean any structured data.

Probabilistic Databases: Wrote novel algorithm for mining and evaluating functional dependencies on probabilistic data, including extending definitions for conditional and approximate dependencies to probabilistic data.

Professional Experience:

Mar 2014 – present: Google Inc.
I am a Software Engineer in the YouTube team at Google.

May – Aug 2011: IBM India Research Lab
Intern: Created a novel algorithm to annotate entities in documents using signals from the entire corpus. Used a linear programming technique to disambiguate entities crawled from various news sources. A patent application was filed for this algorithm.

July 2007 – July 2008: Microsoft India R&D
Software design engineer: Designed and wrote code in C++ for the Applets and Gadgets group in Windows 7.

May – July 2006: Yahoo Software Development, India
Intern: Created a prototype of a new version of Yahoo! Mail that targeted users with relatively older browsers. Achieved an award for exceptional performance.

Nov 2003 – Dec 2006: Innovations Lab, IIT Kharagpur
Active member and Group head of the Java group: implemented a solution to digitize the hall libraries. Implemented a solution for Training and Placement Cell, IIT Kharagpur.
