Dr. Dionysios Raitsos received his BSc in Marine Biology, MSc in Fisheries Science, and PhD in Satellite Oceanography (from Newcastle, Aberdeen, & Plymouth respectively). He worked for 6 yrs as a post-doctoral researcher in Greece (HCMR) and Saudi Arabia (KAUST). He joined the Remote Sensing Group (RSG) at PML in 2013 and worked as a Senior Research Scientist here until 2019.

Dionysis is interested in satellite remote sensing applications in ocean colour, plankton, and fisheries in relation to the regional environmental variability and broader climate oscillations (Red Sea, Atlantic, Pacific and Mediterranean Sea)."

    Full Time - 3 year Fixed Term Appointment 

    Do you have a background in building/developing scientific instrument systems and providing specialist technical support? Do you want to further your career in one of the UK’s leading marine research laboratories, making crucial steps to understanding how the oceans and marine atmosphere influence air pollution and climate?

    Plymouth Marine Laboratory has a strong track record in world leading Air-Sea Exchange (ASE) research. In recent years, the ASE group has had considerable success establishing a coastal atmospheric research station at Penlee Point (https://www.westernchannelobservatory.org.uk/penlee/) and developing the capability to make autonomous direct measurements of air/sea CO2 exchange from ships (e.g. https://www.westernchannelobservatory.org.uk/autoflux/discovery/). We require a Junior Technologist to help us to build upon these successes.

    As a key member of the ASE team your role will be to maintain and improve remote instrumentation at Penlee and on ships fitted with air/sea flux systems. You will drive forward the automation of remote instrumentation and develop novel methods of data acquisition and delivery using embedded PC technologies (e.g. Raspberry PI) and Python scripting. You will be responsible for data processing and quality control and will contribute to scientific interpretation and research outputs. You will be jointly responsible for the day-to-day running of the ASE laboratory and Penlee facility.

    This post is available immediately and for a fixed term of three years. To explore the post further or for any queries you may have, please contact the air/sea exchange group lead (Dr Tom Bell) via careers@pml.ac.uk 

    For this role we are open to discuss the possibility of reduced hours, flexible working or possible job share.

    Closing date: 5pm on Tuesday 10th December 2019

    Interviews will take place on Tuesday 4th February 2020
