University of Wisconsin–Madison biochemistry assistant professor Philip Romero and neuroscience assistant professor Ari Rosenberg are the recipients of 2018 Shaw Scientist Awards from the Greater Milwaukee Foundation. The awards come with $200,000 in seed funding to support innovative research approaches and the career development of young investigators.

Romero’s work uses new technologies to understand how proteins work and how to design new ones. Using computational methods, he is able to analyze large amounts of data that help him investigate the relationships between protein sequence, structure and function. This allows him to pull out sequences that lead to useful properties and design new proteins with desired functions.
His research has many implications because the proteins can be engineered to have specific functions, such as in bioenergy, chemical production and human health. Projects are investigating how to help convert biomass to fuel and develop cancer therapeutics. Along with these applications, the group also focuses on developing new protein engineering methods.
“The Shaw Award will enable us to pursue new high-risk projects that wouldn’t be supported by the standard funding agencies,” Romero says. “We’re excited to think longer term about where our field is headed, and how we can make a large impact on engineering biological systems.”
Romero joined the department in July 2016. He earned his Ph.D. at the California Institute of Technology. At UW–Madison, he is also affiliated with the Department of Chemical and Biological Engineering.
Romero joins a decades-long line of Department of Biochemistry faculty members in receiving the award. In 2017, assistant professor Ophelia Venturelli received a Shaw Award and the year before that, so did assistant professor Vatsan Raman, with many more before them.

Rosenberg’s research recognizes that despite the noisy and ambiguous input received by the body’s eyes, ears and other sensory organs, people perceive the world accurately and precisely. Unlocking how the brain performs this transformation is a path to understanding neurological and neuro-developmental conditions, such as traumatic brain injury and autism.
Using multifaceted experimental and computational approaches, Rosenberg’s lab is quantifying the neural basis of robust perception to ultimately guide development of individualized treatments for brain disorders. It’s an approach whose potential is being realized because of the Shaw Scientist Award.
“Research funding today tends to favor studies that have a high chance of finding an unsurprising result, and discourages more speculative studies that might yield big gains,” Rosenberg says. “For a young scientist like myself, the Shaw Scientist Award eliminates such barriers, making it possible to pursue unexplored research avenues that might not otherwise see the light of day.”
Rosenberg joined the faculty at UW–Madison in 2015 and earned his Ph.D. in computational neuroscience from the University of Chicago. He previously was awarded an Alfred P. Sloan Research Fellowship in neuroscience. The highly sought-after award honors early-career scientists whose achievements and potential identify them as “rising stars.”

“For a young scientist like myself,” the award makes it “possible to pursue unexplored research avenues that might not otherwise see the light of day.”

The Shaw Scientist Awards program began in 1982 thanks to a $4.3 million bequest from Dorothy Shaw, widow of James Shaw, a prominent Milwaukee attorney. In addition to $2 million in special grants, the Shaws’ fund has awarded about $14 million in grants to 73 scientists from UW–Madison and UW–Milwaukee. An advisory panel including scientists representing major U.S. research institutions recommends the winners.
Founded more than a century ago, the Greater Milwaukee Foundation is the region’s largest community foundation and was among the first established in the world.
“Dorothy Shaw, whose generosity made this program possible, has left a tremendous legacy, not only by accelerating the work of stellar young researchers, but through biomedical advances — those discovered as well as those still to come — that her support has seeded,” says Ellen Gilligan, president and CEO of the Greater Milwaukee Foundation. “I congratulate this year’s recipients on their innovation in pursuit of knowledge.”

Biochemistry assistant professor Srivatsan “Vatsan” Raman has received a Director's New Innovator Award from the National Institutes of Health (NIH). The $2.2 million-grants fund high-risk, high-reward research performed by early stage investigators. Compared to traditional NIH grants, the New Innovator Award supports “unusually creative early stage investigators” whose research can have a broad impact on biomedical sciences.
Raman’s project is focused on understanding protein allostery. Allostery is a property by which when something happens to one part of a protein, a signal is somehow communicated to another part of the protein, where another action takes place. This “long-distance” communication is called allostery.

other end of the protein where there is an effect on
DNA. Illustration by Robin Davies.

“Allosteric proteins are nature’s switches,” explains Raman, who is also affiliated with the Department of Bacteriology and the Great Lakes Bioenergy Research Center. “The classical view, one that every biochemistry textbook follows, is that only some proteins exhibit allosteric properties. However, this view is dated. There is increasing recognition that allostery is a fundamental property of all proteins, just as folding is, and that allosteric behavior is more pronounced in some proteins than others. Allosteric proteins regulate many essential cellular processes required for life. They switch states from on to off or off to on and that’s how they turn on and off a very large number of genes. However, sometimes they acquire a mutation that causes the switch to be permanently on or off when it shouldn’t be. This dysfunction is responsible for many diseases, including cancer, because activities inside a cell are no longer regulated.”
Because of their central role in regulation, these proteins are popular drug targets. Raman says almost half of all current drug targets are allosteric proteins. Yet, little is understood about how allostery itself works.
 “So, the thesis of this award is: how does this on/off business work?” Raman says. “Can we figure out the specific amino acids — the smaller units that make up proteins — that allow it to change between on and off? In my laboratory, we develop high throughput methods to probe the role of every amino acid in these proteins to decipher which are involved in allostery.”
Raman explains that their grand objective is to not just study allostery in one or two proteins, but understand the fundamental “rules” of the property. To achieve this, they plan to utilize their data from high throughput analysis experiments together with machine learning to look for commonalities across different allosteric proteins. Then the computer could look at an arbitrary allosteric protein with a mutation and predict the impact of that mutation and possibly how is best to alleviate any detrimental effects.

The NIH Director’s New Innovator Award
supports “unusually creative early stage
investigators” whose research can have a
broad impact on biomedical sciences.

“The broader vision of my laboratory is to develop these tools to advance precision medicine,” Raman says. “Every day we sequence the genomes of patients with diseases, but we have no clue which protein mutations affect function, and how they do so. Wouldn’t it be great if we could create a ‘lookup table’ or a database of mutations that a physician could use to interpret a patient’s genome?
“Drug companies are also very interested in learning how allostery works,” Raman adds. “For example, most drugs target a protein’s active site to block its action. The problem is that many proteins have similar active sites so a drug that targets them can cause harmful side effects. By comparison, allosteric sites are much more specific and understanding them to be able to target them instead can lead us to better drugs. An example of this is an estrogen receptor involved in breast cancer.”
The award is funded by the NIH Common Fund, which supports a series of high-impact programs across the NIH. The New Innovator Award was established in 2007 and supports innovative research from early career investigators who are within 10 years of their final degree or clinical residency. Two other faculty at UW–Madison also received the award: assistant professor of neuroscience Darcie Moore and professor of medicine Nasia Safdar.
Raman’s award is supported by the NIH Common Fund, grant number DP2 GM132682.
