Accueil de Véronica Molina

Dr. Véronica Molina from the Departamento de Biologia. Facultad de Ciencias Naturales y Exactas. Universidad de Playa Ancha (Chile) will be invited by the UPMC as Professor for one month at the LOMIC (september 2015).


Dr Molina has extensive expertise in molecular techniques (metagenomics, proteomics and Q-PCR) and has been working on the regulation of marine nitrogen cycle for the last 10 years. Her research interest are currently devoted to understanding the impact of microbial communities (archaea and bacteria) on the cycling of green house gases in extreme conditions. She is also interested in the capacity of microbial assemblages to process anthropogenic organic inputs derived from aquaculture activities.

Dr Molina is an active member of LIA MORFUN (International Associated Laboratory of Marine Biogeochemistry and Functional Ecology, OOB-University of Concepcion Chile) and has published with Dr Camila Fernandez and Ingrid Obernosterer of LOMIC.

During her stay at LOMIC, Dr Molina will undertake a data mining project from sequences obtained in the frame of the project “Archaeal versus bacterial driving nitrification in the high-altitude saline wetland of Salar del Huasco” (Molina PI, Fernandez co-PI). In particular, she will concentrate on the detection and assessment of genes involved in ammonification and green house gases (N2O) production processes. This should lead to a publishable manuscript during 2015.

A second step will be launching HPLC analyses of samples collected in Patagonian fjords (Puyuhuapi campaign of the COPAS center, ongoing collaboration with LIAMORFUN) and microbial mats obtained in northern Chile.

Also, De Molina is involved in the project “impact of pesticides used in aquaculture on microbial diversity and function”, for which she will start treatment of sequence data obtained during biodegradation experiments carried out in august 2014.
