News and Events

Brandon presents his research to the state legislature and representatives at the Posters on the Hill Conference in Washington D.C.

This is a highly prestigious invitation, as only 1-2 undergraduates from each state are invited every year to attend, and only 2 students from Iowa State University have been selected to attend this event in the past 22 years. He was also recognized with an Engineering Excellence Award from the Institute of Electrical and Electronic Engineers (IEEE). Congratulations, Brandon for representing Iowa State University and the Department of Chemical and Biological Engineering!

Best Wishes!

Radhika starts her post-doc at the National Renewable Energy Lab in Golden, Colorado. We know you will do great things!


Daniel, Hamed, and Marco all passed their PhD qualifier exams!

Welcome Back!

Elspeth returned from her second Center Based Research Experience at Kennedy Space Center. She spent 10 weeks in Florida characterizing her catalysts.

Welcome !

Mathew Laureano joins the Tessonnier group!

Auf Wiedersehen!

Radhika and Elspeth visit the BESSY II Synchrotron to perform Near Ambient Pressure X-ray Photoelectron Spectroscopy (NAP-XPS) at the Helmholtz-Zentrum Berlin, Germany. The work was done in collaboration with Raoul Blume from the Fritz Haber Institute of the Max Planck Society.

CBE Perfect Pitch

Sani, Radhika, and Elspeth participated in the Chemical and Biological Engineering Department’s Perfect Pitch contest. This event challenged all the Chemical Engineering Graduate students to explain their research in just 90 seconds.

The Tessonnier Group welcomes three new PhD students

Marco Nazareno Dell’Anna – Identification and Electrocatalytic Conversion of Bioprivileged Molecules

Daniel Viju Vincent Sahayaraj – Continuous Flow Lignin Deconstruction in Supercritical Solvent Mixtures and Conversion to Renewable Chemicals

Hamed Bateni – Tailoring Metal-Carbon Support Interactions for the Selective Hydrogenation of Multifunctional Chemicals.

Season Chen joins the group as a visiting scholar. Welcome!

Si (Season) Chen, a grantee of the prestigious Fulbright Hong Kong Program, joins the Tessonnier group for a ten-month stay as a visiting scientist from the Hong Kong Polytechnic University. She will be working on Glucose Isomerization. Congrats and Welcome!


Happy Birthday, Elspeth!

The group celebrates Elspeth’s birthday after she returns from her summer-long Center Based Research Experience at Kennedy Space Center in Cape Canaveral, FL.
