About
I am Professor of Informatics and Computing at Indiana University Luddy School, where I direct RedLab and lead a group researching representation, reasoning and artificial intelligence (AI) for data that is messy, incomplete, and spread across sources. These methods are applied in drug discovery, healthcare, emergency response, economics, cybersecurity and defense. I have also launched several successful startups (staring age 12!) and am active in the Southern Indiana startup scene (yes, there is a startup scene here).
I trained as a computer scientist, completing a PhD in computer-aided drug discovery and parallel processing. I spent the first part of my career in the pharmaceutical industry, leading scientific computing teams in computational chemistry and molecular modeling. I came to Indiana University in 2005 from that industry background, which still shapes how I work: I am equally interested in whether something functions in the field and whether it is elegant in theory.
For over fifteen years I practised as a volunteer EMT, search and rescue technician, and emergency manager, which gave me a new lens on technology and data in critical decision making, as well as the human consequences of tech-enabled decisions. The gap between the data that exists and the decision that has to be made is what most of my work is about.
I love creating and exploring new ideas and possibilities. I am a persistent experimenter in all areas of my life, and I read widely outside my field. I write about AI and its wider consequences at Prior Shift, and consult in AI and data science. Originally from the UK; based in Bloomington, Indiana.
Research scope
My research concerns acquiring, building and reasoning over data in domains where data acquisition is difficult, data is incomplete and heterogeneous, and decisions are consequential. Methods include graph, semantic and topological representation, machine learning, embeddings and language models and human-computer interaction design frameworks that put structure in front of the person who has to act.
Application Areas
The mathematical methods apply to any domain where the data is complex, heterogeneous and incomplete. They were developed against the most complex system we know of - the human body - and are now being applied in areas including situational awareness and cybersecurity.
Grounded in
Where the methods were built and where they continue to impact: cheminformatics, bioinformatics, chemogenomics, and link prediction over sparse biological evidence — most recently yielding experimentally confirmed drug candidates for tuberculosis.
Current focus
First responders, disaster responders, and emergency managers have to make decisions in complex, adverse, and data overload contexts. My focus is on filling data gaps, fusing heterogeneous real-time streams, and surfacing the signal in an actionable way in high stress environments.
Extending to
Increasingly decisions have to be made across domains and with overlapping data and expertise structures, for example, in cyber-physical systems. These same methods can be applied at higher or different abstraction levels across domains, maybe even to enable decisions that go beyond human capacity to acquire and fuse data.

Integrating heterogeneous, often messy sources into a single object that permits inference: semantic frameworks, linked open data, ontological annotation, learned embeddings, and the topography of high-dimensional activity spaces. The representational choices made here determine what can subsequently be computed.
