Qadium creates and organizes knowledge about the world's devices. As a Data Scientist at Qadium's early stage, I helped build out the software for several federally awarded DARPA contracts. Later participated as a project lead on the MEMEX project at DARPA. Alongside several academic and non-academic institutions utilized machine learning to fight human trafficking on the Dark Web.

• Authored several software projects developing new graph based entity search technologies for deep and adversarial domains available on DARPA open catalog
• Created new automated methods to analyze textual content on the deep web in order to uncover hidden latent relationships between entities.
• Utilized convolutional neural networks to do image detection written in tensorflow

Blockspring connects your apps to your data. Automate exports, refreshes, and warehousing. Utilizing machine learning algorithms to generate predictive models that provide insight from structured data

• Authored initial core NLP "Blocks" used on the Blockspring platform
• Worked under Peyman Faratin in building NLP stack
• Trained Named Entity Recognizer based on Stanford CoreNER optimized for BLEU scoring

Precision engineering of microelectromechanical systems to specifications of single microns, from virgin silicon wafers through its final packaging and testing

• Applied domain knowledge in material science to engineering problems in nanofabrication
• Used k-means to cluster bins of silicon dies
• Created IOT device for measuring facility temperature and humidity to ensure they stay within control ranges.

2014: Founded the Data Science Student Society DSS@UCSD.

2015: Created UCSD team to compete in SDSU Data Contest: Won Director's Award.
