For almost 30 years, water flow into and out of a cell has been known to be regulated by channel proteins called aquaporins. Because the H2O molecule is forced to cross membranes at certain points on its way from the roots to the leaves, aquaporins are believed to be the main regulators of water flow. Furthermore, even though quite simple in structure, aquaporins come in a variety of different isoforms, each specific to certain membranes. While a lot of research has focused on their structure and function, unfortunately not much is presently known about how these channel proteins control water movements within an entire plant.
To make matters more complex, the different isoforms are expressed in different tissues, have varying substrate permeabilities, and may interact with each other within the membrane. Thus, our understanding of the concept of whole plant water balance is still quite incomplete. My goal is to find out how water molecules are guided along their way through the plant and to eventually use this knowledge to improve plant productivity.
My main aims using the model plant Arabidopsis thaliana are:

Education
9/2008 – Master of Science in Plant Biology
3/2015 Faculty of Biosciences, University of Helsinki, Finland
Master’s project in the field of aquaporin ecophysiology (grade: magna cum laude approbatur)

Current Positions
10/2015 – PhD Student
present Organismal and Evolutionary Biology Research Programme, Viikki Plant Science Centre, University of Helsinki, Finland
My work aims at determining the function of the plasma membrane aquaporins in regulating water flow in the model plant Arabidopsis thaliana. In order to find out how aquaporins control water flow through the plant, I mostly employ ecophysiological techniques such as gas exchange measurements.
5/2015 - Tour Guide and Substitute Teacher

8/2008 – 1/2014, Terminal worker, Substitute Lead Sorter and Facility Security
6 – 9/2015 Coordinator
United Parcel Service Finland Oy, Vantaa, Finland
My responsibilities as a terminal worker were to sort, scan and load packages into containers. In my capacity as a lead sorter, I managed a team of 10 terminal workers to ensure a continuous workflow and coordinated the work in our terminal with the division located at the airport. As facility security coordinator, I enforced correct safety procedures for all packages delivered by air mail, did regular auditions for our security staff and filed daily performance reports.
9/2007 – 5/2008 Non-military Service
Jugendkulturzentrum Gladhouse, Cottbus, Germany
My main tasks included equipment maintenance, preparing events and tending to the facility grounds.
Project management
10/2015 – PhD Student
present Organismal and Evolutionary Biology Research Programme, Viikki Plant Science Centre, University of Helsinki, Finland
For my PhD project, I am solely responsible for drafting schedules, setting up and managing experiments as well as coordinating with other group members and collaborators. As a self-funded student, I also apply for funds and manage the project finances by myself.
Volunteer work
8/2018 – Environmental Committee at the University of Helsinki
12/2020 As a member of the committee, I am involved in planning and preparing events and campaigns that are aimed to implement concrete changes at the university, but also raise environmental awareness on a broader scale.
5/2017 – HOAS (Student Housing) Tenant Committee
4/2020 The committee is meant as a support for tenants giving advice, solving problems and managing keys as well as garden plots. We also manage a budget of 5500€/year to be spend on maintaining and improving the property and surroundings as well as maintaining common spaces. My personal responsibility are the garden plots, assigning them to tenants, maintaining the grounds and organising regular info sessions.
