Summary

I am a teacher of computer science as well as an independent computer science curriculum developer, teaching and developing project-based learning curriculums for secondary school and online educational platforms since 2017. I have a Career & Technical Education teaching credential from CA, USA. I'm also an ESL english teacher, a web and mobile app developer, and a yoga and meditation instructor.

I've recently launched Termeric, which is an online buy-and-sell marketplace for K-12 school subject curriculums.

Before discovering my passion at the crossroads of computers and teaching, I spent seven years during and after my Ph.D. studies at UCLA as a programming languages researcher, focusing on the application of artificial intelligence in programming and software development.

Background

I recently obtained a preliminary Career & Technical Education Teaching Credential in CA, USA. I received my Ph.D. in the area of Programming Languages, in 2013 at UCLA Computer Science Department advised by Todd Millstein. At UCLA, Viewpoints Research Institute, and SAP Labs, I spent seven years as a programming language researcher in the area of language design and the application of Artificial Intelligence algorithms in software development. I am a computer science and programming teacher, curriculum developer, and an independent Android/iOS mobile app developer. I have enjoyed teaching computer science and programming at Garden Grove High School and Living Wisdom High School in Ananda Village in California USA, and at Pathumthep Witthayakarn School in Thailand. I worked with the BSD Education team, developing computer science and technology education project-based learning curriculum and content for secondary school. I also have created online courses in programming, mobile app development for Android and iOS, and high school computer science education for Udemy.com.

Past Research

In the field of programming languages, my work was to contribute towards the design of programming frameworks that allow programs to be specified in as elegant, declarative, and in domain-specific forms as possible, yet be practical enough to have impact in the software community. My main interest is finding practical applications of decision procedures, executable specifications, declarative programming, and constraint solvers in programming. However, my Ph.D. research has focused on utilizing these in software engineering in general: development, testing, debugging, reliability, and education. Aside from their application in the design of languages, I am interested in applying these tools in performing static and dynamic program analyses: verification, synthesis, and program repair.

My research work mantra: Let's use constraint solvers not for program-analysis but for program-ming
