My 101
In biology and medicine, not only has a lot of data already been generated, but technological advances are enabling us to gather more of it faster every year. Having a lot of data, however, does not necessarily mean we have any greater understanding of how things work.
Discovering how diseases begin and how they might be treated comes from putting the data in a context that it can be understood and then putting the data in the right hands to use it. One example of this is human genetics. Humans have about 25,000 protein-coding genes, and we have data on the location of each gene, but we still don’t know what about one-third of them do.
In my lab, we focus on using computers to make sense of the “data deluge” by finding patterns within large databases and using different sources of information to identify and experimentally verify causal relationships buried within the data. For example, we developed a method to predict what this remaining third of unknown genes do. And, with collaborators, we have been able to validate these predictions experimentally, identifying novel genes that play important roles in immune cell movement and function, blood vessel growth, cancer progression, DNA repair and cell division.
Now, recent technological advances in Artificial Intelligence are helping us accelerate our understanding of the patterns that exist across all experiments. Our goal is to push the boundaries of what we know about human genetics and disease using computational approaches, making inroads into this “Final Third” of our genome and understanding the contribution our genes make to both health and disease.
Research
Many scientific questions can be answered with data that already exists. My lab’s goal is to develop methods to accelerate the pace of scientific discovery.
My area of research is in bioinformatics, which uses computational approaches to solve biomedical problems. Generally, my research interests are in developing computational methods to accelerate our movement from data (observations and measurements) to knowledge (predicting cause and effect). Individual case-control experiments are the backbone of the traditional scientific method, but they lack broader context, such as how unique those changes are to the disease being studied. “What has changed?” is an easier question to answer than “How certain are we these changes are real (i.e., reproducible)?” which, in turn, is easier than “What do these changes mean?”. Modern scientific technologies generate tremendous amounts of data, allowing us to contrast new experiments with prior ones, but this comes with challenges.
One arm of my research is data mining. We are interested in integrating and data mining large biomedical databases, like repositories from the National Center for Biotechnology Information, for patterns that can help science accelerate its knowledge regarding the genetic and epigenetic causes that lead to the onset and progression of diseases. Humans have approximately 25,000 protein-coding genes, and we don’t know the functions of about 33% of them. If we add the 30,000 non-coding RNA to this total, approximately 55% are of unknown function. For genes we know something about, the amount of information per gene is often skewed toward those of commercial importance. Emerging data indicates that many, if not most, of these uncharacterized genes are just as important, biologically speaking, as the ones we do know about. We are working on methods of structuring this data using large language models like ChatGPT in combination with vector databases to store and analyze it with artificial intelligence and machine learning methods.
The second arm of my research is developing methods to automate error-checking, both in the scientific literature and public data. Scientific literature is growing exponentially, both in the number of papers published and the size of the papers. Our current peer-review model is being challenged because literature production is outpacing the number of scientists available to review papers, which is only growing linearly. My studies have shown that certain errors and even ethical breaches are slipping by peer review at a fairly constant rate. Fortunately, we can catch some algorithmically. We have included only a few in a prototype web server to check scientific papers at http://pubqc.omrf.org, which we are working to expand to help increase the quality of published science.

Much like the world of college essays, scientific journals are often plagued with authors trying to publish someone else’s work as their own. For Oklahoma Medical Research Foundation scientist Jonathan Wren, Ph.D., the issue hit home as part of his duties as an editor for the journal Bioinformatics, when a reviewer recognized a paper as […]
Rare is the scientific paper today written by a single author. With research being conducted by teams of scientists, most studies now boast a half-dozen or so authors. According to a new study led by a scientist at the Oklahoma Medical Research Foundation, credit for those papers is far from evenly distributed, and the order […]
