Welcome to my webpage, and thank you for stopping by! I'm David Hummel, currently deepening my knowledge in the Economics Ph.D. program at Northeastern University. Over the past five years, alongside my academic journey, I've embraced various roles in external firms. My lifelong fascination with mathematics and logical reasoning has evolved into a profound appreciation for computer science. I'm driven by a desire to harness my skills and make a tangible impact. As you explore further, you'll discover highlights of my professional and academic milestones, my foundational skillset, and the passions I'm currently pursuing.


The Ohio State University, Columbus, OH

BSc in Industrial Systems and Engineering     Aug. 2012 – May 2016

My passion for mathematics and problem solving led me to pursue a Bachelor's degree in Industrial Systems and Engineering at The Ohio State Univeristy. This provided me with a robust understanding of engineering principles, systems optimization, and the interdisciplinary nature of engineering and its applications in various industries. While a senior at Ohio State, I took an Operations Research course which sparked my interest in the optimization practices.

Northeastern University, Boston, MA

PhD in Economics     Aug. 2018 – Present

With renewed appreciation of the generalizable tools Operations Research and Economics offer, I decided to pursue a Ph.D. in Economics at Northeastern University. At Northeastern University, I embarked on a comprehensive study of Economics, diving deep into both theoretical and applied aspects of the field. My journey here has equipped me with advanced analytical skills and a profound understanding of economic principles and their real-world applications.

Professional Experience

Lockheed Martin

In my main project at Lockheed Martin, I combined Business Intelligence tools, VBA, and batch scripting to generate reports by product area. I automated these reports to be sent daily to the inboxes of area managers and displayed them on television screens throughout the facility. This automation enabled managers to spend less time on report generation while giving them a clear snapshot of the manufacturers' performance.

In my second project, I collaborated with the senior in-house Oracle developer. Together, we addressed a challenge in the building process where numerous small parts had to be retrieved from a warehouse and assembled into a kit. We designed an application that expedited the collection of these parts and facilitated the tracking of each piece of equipment throughout the assembly process. This system also accounted for out-of-stock parts, allowing the assembly to commence without them.

I thoroughly enjoyed my time at Lockheed Martin but felt a pull toward acquiring a more versatile toolkit. Drawing from my background in Operations Research and my growing passion for computer science, I chose to delve into Economics, which I saw as the ideal fusion of these fields.

Federal Reserve Bank of Boston

In the Spring of my first year in the Ph.D. program, I joined the Federal Reserve Bank of Boston's Payments Strategies group. I continued working there until the Fall of my second year. During my tenure, I took on various projects. One of my primary responsibilities was the 2019 Federal Reserve Mobile Financial Services Survey, which gathered data from over 2,000 financial institutions about their mobile banking and payment services. When I joined, the team had just completed the survey design. I took the initiative to automate the documentation of returned responses, clean the data, and conduct its analysis. Given the sensitive nature of the information, I exclusively used VBA for these tasks.

In my primary project, I delved into the realm of payment fraud. My responsibility was to create a comprehensive model detailing various types of fraud and their corresponding mitigation strategies. To achieve this, I collaborated with an undergraduate intern whom I managed. Together, we scoured numerous papers on fraud types and mitigation techniques. I distilled the information into its essential components, synthesizing a clear and concise model. My team then introduced this model to financial institutions, providing insights into potential threats and offering actionable strategies to safeguard against these vulnerabilities.

American Antitrust Institute

During the Spring of my third year through to the Spring of my fourth year in the Ph.D. program, I served as a Research Fellow at the American Antitrust Institute. This role provided me with invaluable insights into policy advocacy. I took the lead on several projects, including:


Teaching Intermediate Macroeconomics at Bentley University marked my first solo teaching experience. I then taught a Master's level Econometrics course at Northeastern University. You can explore the lectures for my Econometrics course here. While in the Economics Ph.D. program at Northeastern University, I've had the privilege of teaching the week-long Math Boot Camp for incoming second-year students. I've led this session every year since my second year in the program. In these sessions, I cover topics like Linear Algebra—whose material you can view or download here—and Static Optimization, which you can also view or download here.

In addition to these teaching roles, I served as a Teaching Assistant for Econometrics at Harvard University. At Northeastern University, I've assisted in a range of courses, including Bubbles, Busts, and Bailouts (a deep dive into the causes and aftermath of the 2008 Housing Crisis), Intermediate Macroeconomics, Intermediate Microeconomics, Introductory Econometrics, the Capstone course, and Development Economics.

Academic Research

Work in Progress

Research Assistant

Balancing my roles, I often work as a research assistant alongside my duties as a teaching assistant. This dual responsibility has introduced me to myriad projects, each contributing to my growing and diverse skillset. In one such project, I was the bridge between my manager, Professor Bilge Erten, and a trio of undergraduate students. Navigating this inter-generational dynamic, I emphasized transparent communication, set clear expectations, and nurtured a cooperative and efficient work environment. The following are the more notable projects I have worked on the Professor Erten.


My dissertation comprises three distinct chapters, each reflecting a unique area of research:


During my second summer in the Ph.D. program, I collaborated with a multidisciplinary team of political scientists and public health experts. Our focus was on exploring the connection between political polarization and health outcomes. While the team had already gathered survey data, I took on the responsibility of conducting a literature review. This review helped establish a solid foundation for our modeling framework. I then implemented the model, and our collective efforts culminated in the publication of the two papers listed above.

In addition to my primary pursuits, I've embarked on a journey of continuous learning both out of personal interest and to further hone my technical skills. I've been self-learning C++, sharpening my SQL skills, and diving deep into general computer science concepts through LeetCode problems. My progress can be seen on my LeetCode profile , which is available here. Furthermore, I'm actively enhancing my understanding of Machine Learning by taking courses on Coursera.
