In her free time, she likes to go hiking, jogging, and collecting Snoopy items.


Eduard Puente Massaguer, PhD

Eduard received his bachelor’s degree from the Universitat Autònoma de Barcelona (UAB), where he majored in Biotechnology. He went on to pursue his PhD in Biotechnology at Dr. Francesc Gòdia’s lab, where he worked in the development of new generation vaccines based on virus-like particles (VLPs). During his PhD, he visited the group of Dr. Reingard Grabherr at the University of Natural Resources and Life Sciences in Vienna, studying different strategies to produce VLPs at bioreactor scale. Eduard joined the Krammer laboratory in November 2020, where he works in the development of a universal influenza vaccine based on chimeric hemagglutinins, in collaboration with the groups of Dr. Palese, Dr. García-Sastre and the CIVICs.

Jordan Clark, PhD

Jordan Clark graduated from the University of Glasgow with a BSc (Hons) in Genetics in 2014. Following this, he undertook a BBSRC funded collaborative PhD studentship between the Moredun Research Institute and the University of Glasgow. This lasted from 2014 until 2018 and was supervised by Professor Alain Kohl and Dr Roman Biek at the University of Glasgow, and by Dr Colin McInnes at the Moredun Research Institute. This PhD focussed on the characterisation of louping ill virus (LIV), an important but poorly studied animal pathogen in the UK. In 2018 Jordan joined the Molecular Virology Research Group at the University of Liverpool under the supervision of Professor James Stewart. Here, Jordan studied the innate immune protein BPIFA1/SPLUNC1, specifically the mechanism through which this protein inhibits influenza A virus infection in the respiratory tract. During the COVID-19 pandemic, Jordan switched focus to work on elucidating the phenotypic differences between SARS-CoV-2 variants of concern in addition to testing antiviral drugs, vaccines, and other therapeutics using animal models. Within the Krammer lab Jordan researches the antibody response to SARS-CoV-2, influenza, and hantaviruses. Outside of science Jordan enjoys films, TV, botany, Buckfast, and watching Scotland be repeatedly humiliated at sports.
