Job Description

Applications are invited for two postdoctoral positions in the laboratory of Prof. Subhasis Ghoshal to conduct research on the development of safe and biocompatible nanocarriers for agrochemicals and investigation of their uptake and translocation mechanisms following foliar application in plants. The research is aimed at improving agricultural crop yields while reducing environmental pollution.

The Ghoshal Laboratory offers an enriching environment for advanced research training. The lab has unique instruments for characterizing nanomaterials in complex samples (e.g., single-particle ICP-MS, AFM Raman, Time-of-Flight Secondary Ion Mass Spectrometer, light scattering detectors etc.) and conducts XRF/XAS studies in synchrotron facilities. The positions will be part of an ongoing project involving international and interdisciplinary collaborations and offers the opportunity to work with several laboratories. We promote a supportive, safe and welcoming environment for all in our laboratory.

The positions are available immediately. Review of applications will continue until the positions are filled. The preferred start date is August 2024, but there is some flexibility. The initial appointment will be for one year with possibility for extension for additional years. Candidates should have completed their Ph.D. no more than 3 years prior to the date of joining.

Successful candidates will have an outstanding record of scholarship and doctoral/postdoctoral research related to the areas of research described below. Excellent written and oral communication skills are essential. Candidates will be expected to assist in the training of graduate and undergraduate students, and preparation of research proposals and journal papers. Candidates should be able to work independently and as part of a team with collaborators on interdisciplinary projects. A Ph.D. in environmental, materials, chemical engineering, chemistry, biology or a relevant field is required.

Position 1: Nanomaterials Translocation and Transformation in Plants
The position involves research on characterization of nanomaterials and their translocation transformations in plant tissues following foliar application. Expertise in combining nano/micro-scale imaging with chemical speciation analyses, such as through Time-of-flight Secondary Ion Mass Spectrometry, Raman spectroscopy, X-ray fluorescence, X-ray absorption spectrometry, or comparable bioimaging techniques, is required. Preference will be given to candidates with experience in nanoparticle synthesis.

Position 2: Assessing Impacts of Agrochemical Nanoparticles on Plants, Soil Organisms and Insects
The position involves research on the impact of selected agrochemical nanoparticles on soil microbiota and their function, and on organisms of ecological significance in agriculture. Experience in toxicity assays and genomic analyses is required. Preference will be given to candidates with laboratory experience in working with nanomaterials.

Applications should include:
(i) A cover letter detailing the candidate’s experience and knowledge relevant to the position (please identify Position 1 or 2 in the email subject);
(ii) a detailed curriculum vitae with list of publications;
(iii) copies of two most relevant publications;
(iv) contact information for two references.

Applications should be sent to
