H. Susana Marinho, who holds a PhD in Biochemistry from the University of Lisbon, is an Assistant Professor at the Faculty of Sciences of the University of Lisbon (FCUL), where she has taught 12 different courses in the field of Biochemistry. She has international research experience, having completed a postdoctoral fellowship (1996/97) on the metabolism of 4-hydroxynonenal at the Leiden/Amsterdam Center for Drug Research, Leiden University, Netherlands. She is a member of the Redox Biology group, where she was the leader until 2019. She conducted research at the Center for Chemistry and Biochemistry until 2019, after which she moved to the Center for Structural Chemistry (CQE) (FCT = excellent). Since 2001, she has secured €1,069,502 in research funding (of which €141,736 as principal investigator) through competitive grant applications. To date, she has published 40 articles in peer-reviewed international journals and 8 book chapters (2 of which in a Biochemistry textbook), with 2,365 citations (h-index = 22) in the Scopus database and 3,391 citations in Google Scholar (h-index = 27). Notable achievements include a review article classified as a ‘highly-cited ISI paper’ (top 1%) and publications in top percentile journals, such as Progress in Lipid Research (top 1%) and Antioxidants and Redox Signaling (top 10%). She regularly publishes in high-impact journals in the field of oxidative stress and redox regulation, including Antioxidants and Redox Signaling, Free Radical Biology & Medicine, and Redox Biology. She has supervised or co-supervised 1 postdoctoral fellowship, 3 PhD theses, 13 MSc dissertations, and 7 "Licenciatura" theses (pre-Bologna system). Her area of expertise is biochemical redox regulation, particularly redox regulation and signaling of gene expression and adaptation mechanisms to oxidative stress induced by hydrogen peroxide. This includes the regulation of lipid and membrane metabolism using biochemical, biophysical, and molecular and cellular biology approaches. Her main discoveries include: (i) Lysophospholipid hydroperoxides are substrates for glutathione peroxidase (Free Radic. Biol. Med. 22, 871-883); (ii) The gene expression of antioxidant enzymes is regulated in a complex manner by oxidative stress, not only at the transcriptional level but also at post-transcriptional, translational, and post-translational levels (Free Radic. Biol. Med. 34, 385-393); (iii) Plasma membrane permeability in yeast is regulated by hydrogen peroxide (H2O2), and limiting H2O2 diffusion into cells is an important defense mechanism against extracellular H2O2 (J. Biol. Chem. 279, 6501-6506; FEBS Lett. 578, 152–156); (iv) H2O2 is a regulator of plasma membrane lipid composition and dynamics, particularly microdomains (BBA - Biomembranes 1778, 1141-1147; Free Radic. Biol. Med. 46, 289-298; Prog. Lipid Res. 71, 18-42); (v) In yeast, H2O2 targets for redox regulation include the transcription factor Opi1p, involved in phospholipid metabolism, and the inositol transporter Itr1p (Yeast, 34, 383-395; Arch. Microbiol. 201, 123-134); (vi) H2O2 is not a strong activator of the NF-¿B transcription factor in vivo, except for c-Rel, but it enhances NF-¿B activation by cytokines (J. Immunol. 178: 3893-3902; Antioxid. Redox Signal. 11, 2223-43; Redox Biology 1, 347-352). Beyond her work in H2O2 biology, she has also contributed to biophysics, notably discovering the presence of gel domains in the yeast plasma membrane (J. Biol. Chem. 286, 5043-5054), and to nanomedicine, developing enzymosomes containing superoxide dismutase or quercetin for treating inflammation and ischemia-reperfusion injuries in rat liver (Pharm. Res. 32, 91–102; European J. Pharmacol. Sci. 109, 464-471; Pharmaceutics, 14, 104). She has management experience having served as Deputy Coordinator of the Biochemistry Bachelor's Program and as a member of the Executive Committee of the Center for Chemistry and Biochemistry.
