I am a Data Scientist working under Dr. Brenda Curtis at the National Institute on Drug Abuse (NIDA). Formerly, I was a Senior Data Scientist for the World Well-Being Project at the Positive Psychology Center in the University of Pennsylvania. I am also a PhD student in Computer Science at the University of Pennsylvania working under H. Andrew Schwartz and Lyle Ungar. Research interests include big data analysis of language on social media and how this can be used to predict and gain insight into health and risky behavior.

DLATK is an end to end human text analysis package, specifically suited for social media and social scientific applications. It is written in Python 3 and developed by the World Well-Being Project at the University of Pennsylvania and Stony Brook University.
County Tweet Lexical Bank
County level word and topic loading derived from a 10% Twitter sample from 2009-2015. Anonymized linguistic features extracted from over 1.5 billion English U.S County mapped tweets.
TwitterMySQL is a Python library developed by the World Well-Being Project to pull tweets from the Twitter API and insert them into MySQL.
Reddit crawler with MySQL backend
Flask app for running age, gender and (fake) personality predictions from Twitter data.
Map of Twitter Hashtags in Pennsylvania

ENGR 1101: Intro to Engineering
The purpose of ENGR 1101 is to provide you with an understanding of the study and practice associated with civil, electrical and mechanical engineering and technology disciplines. For the electrical section, you will learn several key concepts such as programming in C/C++, hardware design using breadboards and electrical components, interfacing software with hardware using microcontrollers (Arduino), and an introduction to circuit analysis. The last part of this course will involve the Hovercraft design in which you will learn the techniques of soldering and how to efficiently design a prototype in which it is fully functional using an iPad application as the remote controller.

ENGR 4296: Senior Design Project II
Team-oriented engineering system design problems of various types. Topics proposed and orally presented by students in the initial stage of the course sequence. At completion, the project is demonstrated during an oral presentation and a final written report.

ECE 3613: Microprocessor Systems Laboratory
This course provides hands-on experience in assembly language programming for Intel i186EX 16-bit microprocessor and its hardware system implementation. The laboratory assignments utilize 80X86 microprocessor simulations using Emu8086 (www.emu8086.com) and hardware experiments with the FlashLite186 microcomputer by JK Microsystems (www.jkmicro.com) with processor bus logic and output signal measurements using the TechTools DigiView logic analyzer.
