Institute Announces 2018 Junior Faculty Fellows

The Hariri Institute for Computing at Boston University is pleased to announce its eighth cohort of Junior Faculty Fellows. They are:

The Hariri Institute Junior Faculty Fellows program was established in 2011 both to recognize outstanding junior faculty at Boston University working in diverse areas of the computational sciences, as well as to provide focal points for supporting broader collaborative research in these areas at BU and beyond. Junior Fellows are selected by the Hariri Institute Steering Committee based on nominations received each spring, and are appointed for a three-year term.

The Institute’s Junior Faculty Fellows demonstrate the benefits achieved in making the leap from quantitative, statistically-driven research to computational, algorithmically-driven research, and the program’s success is a tell-tale sign of the increasing importance of the Institute’s mission of bringing the computational lens to bear on our data-driven world.

Commenting on this eighth cohort of Junior Faculty Fellows, Professor of Computer Science and Hariri Institute Founding Director Azer Bestavros said he fully expects to see each fellow develop their research portfolios and grow their academic careers just as their predecessors were able to do.

“The Junior Faculty Fellows is the first program we started at the Hariri Institute,” Bestavros said. “Now, many of our Junior Faculty Fellows are full professors and very successful. They’re sitting on my steering committee, running labs of their own… It’s rewarding to see where our fellows have been and how far they’ve come.”

Over the next academic year, each of the Junior Faculty Fellows will be giving a lecture at the Institute.

Image of Christoph NolteChristoph Nolte studies the effectiveness of international and domestic land conservation efforts. His research asks: where does conservation happen? Why there? And what difference does it make? His research relies on large spatial datasets, long-term satellite observations, economic theory, quantitative causal inference, and field research. Nolte is the lead developer of PLACES (Private Land Conservation Evidence System), a novel database that facilitates the study of conservation effectiveness on millions of private properties in the United States. He conducted empirical research in more than 20 countries in Latin America, Asia, Europe, and the Middle East, and works in English, German, French, and Spanish.

Research keywords: conservation, private lands, remote sensing, spatial big data, quasi-experimental causal inference, automated valuation

Professor Anthony Janetos, chair of the Department of Earth & Environment, said that Christoph Nolte joined Boston University in 2016.  His current research focus, which would provide the core of his effort should he be selected a Hariri Junior Faculty Fellow, is development of new algorithms and models that can be applied to large-scale datasets with the goal of understanding and identifying optimal allocation of existing and potential conservation interventions. Because such intervention are inherently spatio-temporal, these models require data at fine spatial and temporal resolution, but are applied at continental scales, which presents substantial modeling and computational challenges.  Examples include cost, allocation, and impact assessment of private land protection across both North and South America.
