Hanneke Takkenberg

Hanneke Takkenberg is a clinical epidemiologist and professor of clinical decision making in cardiothoracic interventions at the department of Cardio-Thoracic Surgery in Erasmus University Medical Center in Rotterdam. She is married and has 4 daughters.
After obtaining her MD at VU in 1994, she worked for 2 years in Los Angeles, and then returned to The Netherlands to pursue a scientific career in clinical cardiovascular practice. In 2002 she obtained her PhD in cardiovascular clinical epidemiology at Erasmus University Rotterdam and started her research group in Erasmus MC. In 2007 she co-founded with Jolien Roos-Hesselink VENA, the Erasmus MC Network of Academic Women. In 2012 she was appointed professor.
Hanneke is a scientific leader in the field of heart valve disease and currently president-elect of the Heart Valve Society (HVS). Her research focuses on clinical decision making and patient empowerment including translation of this knowledge to clinical practice through the development and implementation of patient information portals and decision aids for patients with heart disease.
Gender diversity and diversity&inclusion as a tool to improve research and achieve an inclusive scientific community are cornerstones of her work as Chief Diversity Officer at Erasmus University (2015-present). Professor Takkenberg is chair of the Erasmus Female Professors Network board and advisory board member for Erasmus Center for Women and Organisations.

Hanneke Takkenberg is a LNVH board member since January 1 2018. 

Sandra Groeneveld

She teaches in the fields of organization theory and public management as well as on research methodology and quantitative research methods and techniques. Her research interests include the structure and management of public organizations, focusing particularly on questions of diversity management, leadership and organizational change.
Before joining Leiden University she was employed at the Department of Public Administration of Erasmus University Rotterdam as an assistant professor (2006-2011) and as an associate professor (2011-2014). From 2009 until 2013 she also served as the executive director of the Netherlands Institute of Government (NIG), the Dutch national graduate school for public administration and political science.

She is currently involved in the establishment of the Leiden Leadership Centre, an expertise center on public leadership at Leiden University.

Sandra Groeneveld is a LNVH board member since September 2018.

Sera Markoff

Sera Markoff works at the interface of astrophysics and astroparticle physics with a focus on the most extreme objects in the Universe, black holes.  

Originally from the USA, after a BSc in Physics at M.I.T. and a PhD in Theoretical Astrophysics at the University of Arizona in 2000, she moved to Germany as a Humboldt Research Fellow at the Max Planck Institute for Radio Astronomy.  After that she returned to M.I.T. as a (US) National Science Foundation Astronomy & Astrophysics Postdoctoral Fellow, and then started as faculty at UvA's Anton Pannekoek Institute for Astronomy in 2006, where since 2017 she is professor of Theoretical High-Energy Astrophysics. She has been awarded several prestigious personal research awards such as the NWO VIDI and VICI, and was co-PI of the seven-institute EU-FP7 Marie Curie Initial Training Network “Black Hole Universe” (2008-2012). In 2014, she was named a Fellow of the American Physical Society, and in 2015 she was the Tinsley Centennial Visiting Professor at University of Texas, Austin.

Sera finds community organisation, activism and outreach important. She helped set up the Gravitation and Astroparticle Physics Amsterdam (GRAPPA) Centre of Excellence at UvA. She helped found the Women in the Faculty of Science (WiF) network at UvA, along with Prof. Marian Joëls, in 2007, and helped initiate the successful MacGillavry Tenure-track Fellowship for women. She enjoys engaging the public, and beyond giving talks also carries out structural activities with elementary school children from diverse backgrounds. She was awarded the Willem de Graaff prize from the Royal Netherlands Astronomical Society in 2019 for her public outreach activities.

Sera Markoff is a LNVH board member since December 2019.

Sandra Ponzanesi

Sandra Ponzanesi is Professor of Gender and Postcolonial Studies, Department of Media and Culture Studies/Graduate Gender Programme, Utrecht University and Head of Humanities at Utrecht University College, the Netherlands. Among her interests is the reception of the postcolonial field in relation to the cultural industry, the understanding of the notion of Europe from a postcolonial perspective, postcolonial cinema studies, and the exploration of digital literacies of migrants in transnational contexts. She is currently project leader of the ERC consolidator grant “Digital Crossings in Europe: Gender, Diaspora and Belonging.” The project aims to investigate the relation between migration and digital technologies, in particular the way in which the ‘connected migrant’ contributes to new forms of European integration and cosmopolitan citizenship. The project explores digital diasporas in relation to issues of gender, ethnicity and affective belonging, focusing on how new technologies enhance new forms of connectivity between the homeland and destination countries, bus also across diasporas. The project pioneers a new interdisciplinary method that combines media studies, postcolonial theories, digital humanities and gender studies, drawing from the humanities and social science.

Sandra Ponzanesi is a LNVH board member since May 2016.

Henriëtte Prast

Since 2005, Henriëtte Prast is professor Personal Financial Planning at Tilburg University.

Henriette Prast is a LNVH board member since July 2017.

Moniek Tromp

Moniek Tromp finished her MSc in Chemistry, with specialisations in spectroscopy and catalysis, at the University of Utrecht (Nld) in 2000. She then obtained a PhD from the same university, in the fields of homogeneous catalysis and time-resolved X-ray absorption spectroscopy with Profs. Koningsberger and van Koten.  After finishing with distinction (‘cum laude’, greatest honours possible) in 2004, she moved to the University of Southampton (UK) for a Post-Doctoral Research fellowship in the fields of heterogeneous catalysis and spectroscopy. In 2007, she was awarded an EPSRC Advanced Research Fellowship to start her own independent academic career (and became lecturer). She moved to Germany in 2010, where she took up a position as professor in Catalyst Characterisation at the Technical University Munich. In 2014, she decided to come back to the Netherlands, where she has been working at the University of Amsterdam. From July 2018 she has taken up the Chair of Materials Chemistry at the Zernike Institute, University of Groningen.

She has been awarded prestigious fellowships/awards like the EPSRC Advanced Research Fellowship, NWO VIDI and the NWO Athena prize. She is active in numerous science advisory and review panels of large research facilities and universities internationally, part of a European Science Strategy team for large research facilities in Europe, has published over 120 papers in high profile journals and given over 100 invited lectures worldwide. She is chair of the Dutch Catalysis Society (of the KNCV). She is co-chair of the organizing committee of the annual conference on Catalysis in The Netherlands. Gender and diversity are important for her and she has been active as Gender Equality Officer (D) and is now developing programs for primary school on science and engineering as well as gender bias issues. She is also chair of the Rosalind Franklin Fellowship program of the Faculty of Science and Engineering at the University of Groningen. Her research focusses on the development and application of operando spectroscopy techniques in catalysis and materials research (incl. fuel cells, batteries, photochemistry, as well as arts) with a focus on X-ray spectroscopy techniques.
