Warm welcome to my homepage! This is where I post my academic work.


I am an assistant professor of Information Systems and Operations Management at Emory University's Goizueta Business School.

I study operational issues surrounding the new product development process. I look at the interplay between design and technology, how breakthrough ideas come about, and when and why collaborative efforts sometimes fail in the development of products and services. I teach the undergraduate process and systems management course at the Goizueta Business School.

I received my BS degree from UC Berkeley, MS degree from Stanford University, and my PhD degree from INSEAD. Before my PhD I worked on technology development at PSA International, a global transportation company.

Papers (published / working)

On Styles in Product Design: An analysis of US design patents (Management Science 2018)

- with Jürgen Mihm and Manuel Sosa

We show how one can identify styles (categories of product design that are perceived to be similar) using design patents. Using this data set we show that (i) style turbulence (unpredictable changes in style) is increasing over time, and (ii) technological turbulence (unpredictable changes in technology) have a U-shaped relationship to style turbulence. We are using this data platform to study other questions (see e.g., "Optimal Distinctiveness Revisited" below). Check out www.stylesinproductdesign.com for the data.

Contracting in Medical Equipment Maintenance Services: an Empirical Investigation (forthcoming in Management Science)

- with Francis de Véricourt and Omar Besbes

In this paper we look at how coordination issues arise in a service context. Consider equipment maintenance - both the maintenance service provider and the equipment operator play important roles in equipment upkeep. However one party may potentially free-ride on the other's effort. Using data from a major medical body scanner manufacturer, we find that such problems impose a heavy cost in the maintenance of medical body scanners. Our results highlight important trade offs that product makers face as they edge into the after-sales services market.

Revisiting the Role of Collaboration in Creating Breakthrough Inventions (Revision at Manufacturing & Service Operations Management)

- with Jürgen Mihm and Manuel Sosa

The idea of the lone inventor is frequently lambasted as a myth or a romantic image. But is it really? In our study using technological and design patents we find that the decomposability of the invention significantly moderates the effectiveness of the lone inventor. Particularly, tasks that are less decomposable relatively advantages the lone inventor. We also show that lone inventors working on non-decomposable inventions and who have collaborated widely in the past outperforms even teams.

I grew up in Malaysia and Singapore. Love history/fiction, traveling, running, (and now less actively) basketball and RPG games.
