Research Opportunities in planetary science

Available OPEN positions (last modified, 17-05-2020):

• Available positions in Max Planck India Partner Group at NISER, funded by Max-Planck-Gesellschaft zur Förderung der Wissenschaften (MPG):
  • 2 Ph.D. students / 1 Postdoc, for highly motivated and hard-working students/researchers from Geoscience/Physics/Chemistry background (for PhD through NISER PhD advertisement and Exam). Candidates with good programming skill (in python/Matlab/IDL) is preferred.
  • Internship & Dissertation upto 6 months with stipend / financial support, for MSc/BTech/MTech students from Geoscience/Physics/Chemistry/Computer-Science. Students with profound programming language are highly encouraged. Interested students are welcomed for online mode of project and work.
    • Nature of project and work: The project is focussed on spectral analysis of ammoniated absorption feature on the largest asteroid Ceres and their geologic and geochemical study using NASA Dawn data (Framing Camera /FC and Visible and Infrared Spectrometer / VIR). The expected outcome of this project is to understand the origin of asteroid Ceres, whether formed in outer solar system and migrated later, or formed in situ at the present inner solar system location.
    • Collaboration: The project is in collaboration primarily with MPS (Dr. Andreas Nathues), and also others (Edward Cloutis / University of Winnipeg, Canada;  Prof. Kurt Mengel / University of Clasuthal, Germany; Dr. Jean-Philippe Combe / Bear Fight Institite, USA). 
    • Work environment and culture: The researchers will get the opportunity to work in an ambient international research environment and space to train themselves as a self-reliant and independent researcher. Oportunties to visit the collabotaors and their labs shall be provided and also opportunities to present their work in national/international conferences in order to motivate and reward the researchers hard work and only the hard work. 
• NISER postdoc postion for 2+1 year who will be interested to work in areas of surface compositional and morphological studies of inner solar system rocky and outer solar system icy bodies, geologic and geochemical evolution, planetary geology and early Earth geology, asteroids and comets, meteorites and planetary analogue/sample, etc. PhDs with Planetary Science / Geoscience / Physics / Chemistry or relevant background may apply. Candidates with good expertise and research quality in the mentioned areas are preferred. The position is for three years, subject to performance and review each year. Providing opportunities to work with various planetary science datasets in close collaboration with leading national and international institutes and experts in the field, and a Working culture with promising science results and publications in reputed peer-reviewed journals, are the mandate for opening the postdoc position. For more information, please contact via email, and details of the school and the advertisement are in https://www.niser.ac.in/notices/2019/recruitments/PDF-SEPS.pdf

• NISER PhD postion 2020, as per NISER advertisement, in areas of surface compositional and morphological studies of inner solar system rocky and outer solar system icy bodies, geologic and geochemical evolution, planetary geology and early Earth geology, asteroids and comets, meteorites and planetary analogue/sample, etc.
