Biography

I studied biology in University of Patras, Greece and received the Greek equivalent of a first class degree in Biological Sciences in 2005.  My undergraduate dissertation involved extensive research over a 2-year period resulting in two first author publications in peer-reviewed journals (Yiotis et al., 2006; Yiotis et al., 2008). My research focused on the physiological properties of Calicotome villosa and revealed the eco-physiological significance of the bi-modal annual photosynthetic pattern of its photosynthetic organs. I consider my fourth year project a milestone in my research career as it gave me the opportunity to gain valuable research experience, acquire a deep understanding of plant biology and taught me the importance of dissemination in peer reviewed literature.

In 2006 I was selected through a competitive interview process to start my Ph.D. under the joint supervision of Professor Yiannis Manetas (Plant Physiology) and Professor George K. Psaras (Plant Functional Anatomy). Building on my previous experience on Plant Physiology and Functional Anatomy, I continued researching the unique characteristics and eco-physiological significance of photosynthesis in foliar and non-foliar photosynthetic organs, while at the same time I became engaged in several other research projects. My research activities during my Ph.D. resulted in five publications in peer-reviewed journals, including three first author publications (Kotakis et al., 2006; Konoplyova et al., 2008; Yiotis et al., 2009; Yiotis & Manetas, 2010; Yiotis & Psaras, 2011). After fulfilling my compulsory army service, I obtained my Doctorate of Philosophy degree in Plant Physiology (Division of Plant Physiology, Department of Biology, University of Patras, Greece) in 2012.

In 2012 I was successfully appointed as a senior, European Research Council post-doctoral fellow in Professor Jennifer McElwain¿s interdisciplinary research group at University College Dublin. My role in the team is to drive the plant physiological and eco-physiological aspects of the ERC OXYEVOL project. My research focuses on how simulated  changes  in  Earth¿s  atmospheric  composition  at  different  intervals  in  Earth history influenced photosynthetic physiology in different plant functional groups. As the main aim of my investigation is the unravelling of the input-feedback relationship between land plants and Earth¿s atmosphere, my work has significant impact for the field of Global Change Biology and Ecology, as my findings can be used for projections of future plant communities¿ composition under high atmospheric CO2 concentration. The quality and importance of my present work has been repeatedly acknowledged in some of the most prestigious   conferences   in   the   fields   of   Plant   Physiology, Plant Evolution and Palaeobotany and five relevant publications are currently in press, in review or in preparation. My duties also include the co-supervision of the Ph.D. student Christiana Evans-Fitzgerald, training of undergraduate and masters students that join our group and the organization of workshops. In addition, I have recently joined a multidisciplinary Science Foundation Ireland-funded team in an 11-week fieldtrip in the Americas  (7  sites  in  Maryland,  Puerto  Rico and Alaska) and Fiji where I assessed  the photosynthetic and stomatal conductance responses of 68 species under rising atmospheric CO2  concentration. I deem the results of significant importance and expect them to be published in some of the highest impact journals in the field.

In 2016 I was awarded a 92000 euro Post-doctoral fellowship by the Irish research council for my project entitled "Futu-rye". The aim of my project is the identification of key traits associated with increased yield and resilience in grasses under future climatic conditions.

Outreach Activities

2013-2017         I have given several tours of Péac (Program for Experimental Atmospheres and Climate) facility to prominent visiting scientists and groups of students.

 

2016        Participated in UCD's Consultation Workshop for the Campus Engage Engaged Research Working Group. Engaged research describes a wide range of rigorous cross-disciplinary research approaches and methodologies that share a common interest in collaborative engagement with the community and aim at improving, understanding or investigating an issue of public interest or concern, including societal challenges. The Consultation Workshop will feed into the Campus Engage IRC National Report guidelines. This will be a framework for engaged research techniques and set recommendations for policy makers, national and EU funders.

Research

Research Interests

My research interests lie in the areas of Plant Physiology, Plant Eco-physiology, Plant Anatomy and their interactions. I am particularly interested in the input-feedback relationship between plants and Earth's atmosphere. My research focuses on the impact of the atmospheric composition on plant evolution and the effects of climate change on plant physiology, productivitand the composition of plant communities.

Teaching

Teaching Philosophy

My perception of the role of the academic teacher is that instead of strictly delivering knowledge, s/he firstly has to make the students think ¿out of the box¿, and secondly teach them how to construct their own knowledge.
