Quaife advances to Associate Professor

The College of Arts and Sciences, Florida State University, and the FSU Board of Trustees recently awarded Dr. Bryan Quaife tenure and promotion to Associate Professor. Quaife joined the Department of Scientific Computing as an Assistant Professor in the Fall of 2016 after completing a four years as a postdoctoral associate at the University of Texas at Austin. His research seeks to develop and implement numerical methods to efficiently and accurately describe both slow (groundwater flow, nanorod and biomembrane suspensions) and fast moving (fire and plumes) fluid flows.

Lemmon’s research among most cited

Several Florida State University researchers are among the most cited academics worldwide, according to the annual Highly Cited Researchers 2021 list from Clarivate, a data and analytics company.

Three current university faculty members — Professor of Scientific Computing Alan Lemmon, Associate Professor of Biological Science Emily Moriarty Lemmon and Professor of Psychology Thomas Joiner — as well as the late Michael Davidson, the former head of the National High Magnetic Field Laboratory’s optical microscopy program, are on this year’s list.

Population Geneticist awarded NSF Grant

FSU professor and population geneticist Peter Beerli and mathematician Somayeh Mashayekhi, assistant professor at Kennesaw State University (GA), have been awarded a National Science Foundation grant that will help them study how to curb the effects of pathogens or improve the survival of endangered or commercially exploited species. Their research proposal focuses on and challenges the assumption that number of offspring in species remains constant across generations and is independent of the environment; the resulting improved population modelling will increase accuracy and decrease bias of population size estimates.

Natural populations live in heterogeneous environments, and individuals in these populations have different chances to produce offspring. In contrast, current inferences of population genomic data are coalescence-based and assume environmental homogeneity within a population. Additionally, the commonly used coalescent framework assumes a variance of relatively narrow numbers of offspring.

“These assumptions sometimes lead to interesting disconnects between theoretical expectations and observations. For example, the genetic variability of a population may suggest there are some number of individuals, but observational data show that there are many more individuals than the theory allows,” Beerli said.

The grant will help Beerli and Mashayekhi study the effect of dissimilarities in offspring production of a population using a new theoretical framework that can handle heterogeneity. These new methods will be incorporated into Beerli’s widely-used open-source computer software, MIGRATE. MIGRATE uses genomic data to infer population genetic parameters, such a population size, immigration rates, and population divergence times.

Beerli is enthusiastic about this work and about continuing the collaboration with Mashayekhi who was a postdoc in his group before she moved to Kennesaw State. “I hope this is a long and fruitful collaboration. We envision that our method - the fractional coalescent - may lead to many improvements of the standard population genetic theory.”

Beerli and Mashayeki’s grant, Reproductive heterogeneity in the structured coalescent framework, was funded by the National Science Foundation through DBI, the Division of Biological Infrastructure. The division advances fundamental biological research to transform the future by investing in innovation and capacity-building cutting edge research infrastructure for fundamental biological science.

Shanbhag to appear on Ask a Scientist

This week, Professor Sachin Shanbhag will appear as a guest with host Professor Ken Hanson from the FSU Department of Chemistry. Now in it’s seventh year, Ask a Scientist has been recently transitioned to an online platform, and to a new name and focus. The show’s new name - Ask a Scientist Gaming – combines game play with expert science. Shanbhag and Hanson will be live streamed while playing video games and answering questions.

You’ll find information about and links to the upcoming live-stream [8pm on Wednesday, July 21, 2021] at Twitter and Twitch.

To learn more about Shanbhag’s research, visit his group’s website.

Arts & Sciences launches new grad major

The College of Arts and Sciences recently announced a new degree program in Interdisciplinary Data Science. The new program is a collaborative, cross-departmental effort between Scientific Computing, Statistics, Mathematics, and Computer Science. Department of Scientific Computing Chair Gordon Erlebacher conceptualized, then spearheaded the effort to implement the major.

The data science major will feature a range of current and new courses – many in the student’s chosen focus area – that span the four collaborating departments. The new program's emphasis will be a focus on machine learning and artificial intelligence, along with the necessary support tools, including issues such as data cleaning, feature construction, statistical analysis, database management, data privacy, regression, and a multitude of machine learning artificial intelligence techniques.
