What I've done

Zillow Group

January, 2021 - Present

Applied Scientist

It turned out that the awesome people at Zillow wanted me back! Since January of 2021, I have been working at Zillow Group’s economic research as an applied scientist. The combination of intellectual freedom and stimulation, vibrant working environment with some amazing coworkers, great benefits and the work-life balance that Zillow offers is truly unique. I am blessed to call this place my work.

Cornerstone Research

August, 2020 - January, 2021

Associate Economist

Following my ventures in the tech world with Zillow, I decided to dip my toes into the world of economic/litigation consulting. It was an eye-opening experience in a world I knew very little about. Working with some incredibly smart and hard-working people, from junior analysts to principals and VPs, I helped with modeling rebuttal analysis, critiquing opposite side’s econometric methodologies and reading literature to recommend analysis strategies.

Zillow Group

June, 2020 - August, 2020

Economist Intern

Though I had worked part-time and partnered with several companies and organizations before, interning at Zillow was my first professional experience of such magnitude. I was tasked with identifying business areas of potential improvement and to construct behavioral theory-backed hypotheses about the impacts of potential interventions. I designed and conducted an online behavioral experiment and I communicated my findings and recommendations to relevant stakeholders.

USC Center for Economic and Social Research (CESR)

May, 2017 - May, 2020

Research Scientist

I’ve had the pleasure of being part of the CESR family for three years as a research assistant to the director, Arie Kapteyn. Apart from my main responsibilities of developing our paper “Relativity and Habit Formation in Life Satisfaction. (see Research)”, I have collaborated with several other researchers, worked with worldwide surveys of life satisfaction (Gallup World Poll, Eurobarometer, Health and Retirement Survey, etc) as well as   assisted in the writing of two grant proposals to the National Science Foundation.

City of Los Angeles - LA Data Science Federation

September, 2017 - June, 2018

(Graduate) Data Scientist

Formed a team of PhD students and collaborated with City of LA officials and policymakers to obtain real estate and affordable housing data in order to analyze the impact of the introduction of affordable housing on real estate prices. The experience of working with policymakers on a very real problem that is plaguing Los Angeles was very special, one that I have learned so much from. We estimated the average treatment effect using a difference-in-differences design and presented results at the LA City Hall and the quarterly meetings of the LA Data Science Federation (DSF).


January 2017 - July 2017

(Graduate) Data Analyst

I was brought into this project by a mutual contact. I worked alongside the company’s Data Science team to model advertising attribution data from several of their client companies. We estimated Shapley values and impulse response functions using Python. This was my first, non-academic experience where I utilized my econometric skills to think about, model and estimate business questions.

Los Angeles Behavioral Economics Laboratory, USC

September, 2016 - December, 2016

Research Assistant

I began my involvement at LABEL as a participant in the lab’s weekly meetings, led by Profs. Juan Carrillo and Isabelle Brocas, in my second year of the PhD program. During my time with LABEL I assisted in the running of experimental sessions, promoting student participation for the lab in various events and helped analyze a dataset from an experiment. My assistance was recognized in this paper.

Economics department, USC

August, 2016 - May, 2017

Teaching Assistant

Teaching assistant for two masters classes in microeconomic analysis and an upper-level undergraduate class in Economics of happiness. Being a TA for two sections of the same class (microeconomic analysis) taught by two different instructors was an invaluable lesson in teaching given the variability in the approach to the teaching of the same material.

Iceline Cyprus

June, 2013 - Apr, 2015

Operations Analyst

I help the company set up and analyze marketing experiments in their retail stores operating in Nicosia, Cyprus. I also assist in analyzing other consumer data and consult in various strategic and financial decisions. I mostly work remotely in a part-time basis, often spending physical time there during summers and winter breaks. 

Universitat Pompeu Fabra - Barcelona GSE

September, 2013 - June, 2014

Teaching Assistant

My first experience as a teaching assistant. I was responsible for leading the TA sessions in a class for Cost Accounting and for leading the sessions as well as evaluating the final presentations for a class in consumer behavior. 

Center for Decision Research and Experimental Economics, UoN


Research Assistant

My first research experience was as an undergraduate student assisting with the analysis of data from an experiment under Dr. Daniele Nosenzo. Subsequently I was tasked with helping several PhD students in the department on numerous projects (all in the area of experimental economics). My assistance was recognized in this paper.

Cyprus National Guard

2008 - 2010

Sergeant of Infantry and Sapper

Completed my mandatory 24-month military service at the Cyprus National Guard as a sergeant of infantry with the specialty of sapper.

Where I've been educated

University of Southern California

August, 2015 - December, 2020

Ph.D. in Economics

I joined the department in 2015 as a PhD student. Since then I passed my core examinations at the end of my first year and my qualifying exam in the fist semester of my fourth year. I am now working towards my thesis and job market paper. My main research area is behavioral economics and information economics. During my time I have explored my interdisciplinary interests in Psychology and Computer Science by collaborating with colleagues on projects related to the applications of AI and Machine learning in society.

University of Southern California

May, 2017 - December, 2018

M.S. in Computer Science

I took my first class of Algorithms in the summer of my second year as a PhD student in Economics. It was one of the most interesting class I had ever taken and I was hooked. Since then I kept taking CS classes concurrently to my PhD: Machine learning, Database systems, Foundations of AI, Computational social sciences and AI in society.

Barcelona Graduate School of Economics

September, 2013 - June, 2014

M.S. in Economics

The Barcelona GSE master program in Economics is one of the best preparations in Europe for US-based PhD Economics programs and that’s why I joined – with the goal of getting in a US Econ program. Even though I was subsequently offered a place to stay in their PhD program I elected to keep pushing for a US school. Check out a video of me discussing the program here

University of Nottingham

September, 2010 - June, 2013

B.S. in Economics

Being interested in both Economics and Psychology as a high school student, it was an easy choice joining Nottingham due to their work in behavioral economics (the beautiful campus helped nudge my decision too!). Academically I took the econometrics route (7 classes), behavioral-experimental and mathematical economics, among others. I achieved a “first-class” degree classification (top 5%). Beyond academics, I was elected as the course representative in two out of my three years there, took an exchange semester abroad, participated in a summer program at the University’s China campus, and was awarded the Nottingham Advantage Award among others. Check out my alumni profile here.

My team won the first price for the best business idea developed.

Online Learning

2012, 2015

Online Courses

Online learning and MOOCs is an area that excites me. I have followed numerous classes, mostly on programing, but also on various other topics. On a few of such occasions I signed up to receive a certificate. I couldn’t recommend online courses and resources enough for learning and exploring topics of potential interest. If you’re interested check out my “online learning” resource here.

Our initiative gained a lot of attention of the local media at the time. See here.
