Overview

I’m an artificial intelligence researcher and entrepreneur whose primary goal is to provide quality education to all students worldwide. In addition to core technical competencies in AI and software, I’ve cultivated soft skills in leadership, client development, and communication.

Vision

I wrote the book Education: The Next Hundred Years, available through Barnes and Noble and as a Kindle Book on Amazon. The book combines insights from my research, teaching, and consulting experience to provide a roadmap for transforming education over the next century using emerging pedagogical and computational technologies.

Company

I founded Edapt Technologies, which incorporated in November 2021. Within 5 months, we developed a financial literacy assessment suite to help schools in Rhode Island meet a newly legislated graduation requirement, and we became the official state-recommended measure of proficiency. We are now working with multiple national organizations to deliver and improve financial literacy education at scale. Our efforts have been recognized by multiple non-profits and by the state treasurer.

Other Business Experience

I’ve consulted on applications of AI for Speedio in Brazil, Special A Education in China, and several organizations in the US. I’m a board member of the Franklin Center For Innovation (FCFI).

I also had the privilege of participating in the 2022 cohort of the Techstars Alabama EnergyTech Accelerator as the founding CTO of PowerTechs Incorporated, a company applying assessment technologies to professional training in the energy industry. Despite substantive differences in culture, language, and professional background, (and an initial 12-hour timezone difference,) my cofounder and I together received mentorship from a diverse group across the energy and entrepreneurship communities, found a market niche, and successfully landed our first pilot customer. (I also rapped about EnergyTech startups to a packed theater!) After the better part of a year, I made the difficult decision to transition out of the company in order to refocus on high-leverage opportunities for technological innovation in key educational processes.

AI Competencies

I have research experience in many flavors of Machine Learning, with a specialization in Reinforcement Learning and Reinforcement Learning Theory. The core of my doctoral work was on the application of machine learning and other innovations to educational problems to improve the scalability and equity of educational innovation. Some of the problems I’ve developed models for include adaptive assessment, spaced repetition, and content evaluation and recommendation.

Dissertation

My dissertation, Query Strategies for Directed Graphical Models and their Application to Adaptive Testing, brings together machine learning, computer science theory, and education research to develop scalable and effective methods for generating assessments for new topics. This is an important step forward in education research, as it allows us to easily create and, consequently, use rigorous measures of learning to evaluate educational interventions, pedagogy, and policy. My thesis defense is also available on YouTube.

Video Course

I created the video course “Hands-On Artificial Intelligence for Small Businesses”, published through Packt. This course covers several main types of machine learning, and each section discusses a common business problem that can be solved using a technique from the course, including everything from understanding your customers better to making automated recommendations that improve over time. This course also introduces artificial neural networks, t-SNE embeddings, and Thompson sampling for multi-armed bandit processes.

Other Experience

• Interviewed by CEST (Centro de Estudos Sociedade e Tecnologia) about The Future of AI in Education in 2022.
• Invited speaker at the 1st Conference in the Middle East on AI in Higher Education, speaking on “AI and Data Privacy in Higher Education” in late 2021.
• Reviewer for AAAI 2022, IJCAI-PRICAI 2020.
• Invited to deliver an hour-long talk at IM DATA 2019 on applications of AI to education, and then moderate a panel discussion on a similar topic.
• Interned as a Data Scientist at Udacity in 2017. My work there involved analysis of data from millions of students to provide better course recommendations.

Math Expertise

I also have a thorough background in mathematics and probabilistic analysis. I published these papers as an undergraduate:

• AAAI 2016: “A Tool to Graphically Edit CP-Nets”, a short conference paper on a tech demo for a web-based tool that allowed editing and analyzing an annotated directed-acyclic-graph structure called a CP-Net.
• AAMAS 2015: “Probabilistic Copeland Tournaments”, a short conference paper I contributed to that deals with the computational hardness of a particular probabilistic inference problem.
• J. Phys. A 2015: “Generating random walks and polygons with stiffness in confinement”, a journal paper describing sampling methods for random polygons in 3-space under conditions that model the position of DNA in a viral capsid. This was the culmination of several years of research, started when I was 17 years old.

Software Competencies

• Full-stack development using React, Ionic (UI framework), and Firebase (backend database, functions, and authentication) for three interconnected web apps/services using TypeScript.
• Full-stack development using Ruby on Rails for two single-server projects. Additional experience with Django and Angular.
• Fluency in Python, with significant project experience in Java, Ruby, C++, Mathematica, Matlab, and JavaScript.
• Professional experience with Anaconda (Python scientific computing collection), PyTorch (deep learning library), and implementations of a variety of deep learning and other machine learning techniques.
• Experience in Lisp, Visual Basic for Applications, and Racket.
• Knowledge of design patterns, software architecture design principles, and repository management using git.
• Hobbyist game designer/developer.

Teaching

• Freelance Teaching: Private math and programming instruction for a variety of courses, including “Intro to Programming through Games”, “Algorithms and Competitive Programming”, and “Intro to Machine Learning and Research”.
• Consultant: Ran a 3-day machine learning boot camp for the Woods Hole Oceanographic Institution.
• Online Courses: Ran an online course that served as a combined introduction to computer science and number theory.
