Lucas Antony

Lucas is originally from Marshall, Minnesota, located in the southwestern part of the state. In 2011, he graduated cum laude from St. Olaf College with a BA in mathematics and chemistry. During his time at St. Olaf he participated in the Budapest Semesters of Mathematics program in spring 2010, the Summer Institute of Biostatistics at the University of Wisconsin-Madison in 2010, and also worked with the City of Northfield in January 2011 as part of the math practicum at St. Olaf. He then began graduate school at the University of Wisconsin-Madison in the biophysics program, where he joined the research group of Professor Juan de Pablo in 2012. He followed Professor de Pablo to the University of Chicago where he is now completing his PhD research. Besides thinking about the properties of organic glasses, Lucas enjoys endurance athletics such as cycling and running. 

Recently, it has been shown both experimentally and computationally that the formation of remarkably kinetically stable glasses is possible. Such glassy materials have superior thermodynamic and mechanical properties that are of interest not only for applications and technology but also for the fundamentals of glass transition and super cooled liquid state.

Some areas of focus in the group's work are to understand the mechanisms and to validate the principle ideas of stable glass formation. They have developed an efficient way to obtain stable glasses by molecular dynamics simulations and other computational methods. Controlling the enhanced mobility of molecules can lead to more relaxed configurations and more easily form stable materials. Characterization and comparison of the stable glasses’ properties against ordinary glasses’ properties provide valuable insights and allow the researchers to obtain sudden structural differences between ordinary and stable glasses.
