[Grad-postdoc-assn] Postdoctoral Research Associate at UIUC: Modeling nitrogen and hydrological dynamics using the Ecosys model for U.S. agroecosystems

[Paula Fisher]

*******************************
*Postdoctoral Research Associate at UIUC: Modeling nitrogen and
hydrological dynamics using the Ecosys model for U.S. agroecosystems. *

One Postdoctoral Researcher Position in the Department of Natural Resources
and Environmental Sciences (NRES) and National Center for Supercomputing
Applications (NCSA) at the University of Illinois at Urbana-Champaign
(UIUC), full-time, 100% (2-year duration, with possibility of extension,
contingent upon performance and funding).

*Summary:* The successful candidate will use the advanced Ecosys model (
http://ecosys.ualberta.ca/) to characterize and predict nitrogen and
hydrological dynamics for the agroecosystems of the US Corn Belt under
current and future climate. The simulation will be hyper-resolution (a few
meters to 1km) and for broader spatial scales (the whole US Midwest). The
work directly contributes to developing viable adaptations (e.g. agronomy
practices, cover crop, viable-rate fertilizing) to improve the resilience
and sustainability of US Midwest agriculture, which currently produces ~
45% and ~30% of the world’s corn and soybeans, respectively.

*Specific responsibilities* include: implementing and calibrating the
Ecosys model to integrate multi-source observations (field trials,
watershed data, surveys, and satellite) to simulate crop yield, nitrogen
dynamics and hydrological fluxes for US agroecosystems; developing/building
new modules for Ecosys; conducting regional simulations for current and
future climate conditions; preparing peer-reviewed publications and
education materials; managing projects and reporting; and communicating
research at professional meetings.

The successful applicant will be working with a team of scientists in earth
system modeling and ecosystem dynamics, including Dr. Kaiyu Guan in UIUC (
http://faculty.nres.illinois.edu/~kaiyuguan/), Dr. Jinyun Tang in Lawrence
Berkeley National Lab (https://eesa.lbl.gov/profiles/jinyun-tang/), Dr.
Robert Grant in University of Alberta and also the developer of the Ecosys
model (https://www.ualberta.ca/agriculture-life-
environmentsciences/about-us/facultylecturer-directory/robert-f-grant), and
Dr. Symon Mezbahuddin in Alberta Agriculture and Forestry (
http://www.agric.gov.ab.ca/app88/loaddetail?id=126586&action=6&search). The
work includes travels to the Berkeley National Lab or University of Alberta
for extended training. The applicant will be routinely working on Blue
Waters supercomputing system (https://bluewaters.ncsa.
illinois.edu/blue-waters), the most powerful supercomputer in U.S.
universities.

*Qualifications*: Applicants should have a Ph.D. in earth and atmospheric
science, meteorology, hydrology, environmental engineering, physics,
mathematics, or a closely related field. Prior research experiences in
Earth system modeling (e.g. CLM) and data assimilation are highly
preferred. Strong programing skills (e.g., Python and Fortran in the Linux
environment) and prior experience in supercomputing or big data analytical
systems is required, as the applicant will be working routinely in the Blue
Waters supercomputer environment. Candidates will be considered if
graduation with a Ph.D. is expected by the targeted starting date.
Proficiency in spoken/written English is mandatory. The appointment is two
years (renewed annually) and may be extended, contingent upon the
performance. Salary is competitive and commensurate with experience in
relevant research.

*Starting Date*: Ideal starting time is March 1, 2018, but negotiable. The
position is open till filled.

*Application Process*: To ensure full consideration, qualified candidates
must send a cover letter, CV, and contact information of three references
via e-mail to Dr. Kaiyu Guan (kaiyug at illinois.edu) and Dr. Jinyun Tang (
jinyuntang at lbl.gov). All requested information must be submitted in order
for your application to be considered. Incomplete applications will not be
considered. Applicants will be immediately reviewed upon receiving the
application while the search may continue until the position is filled. For
further information, please contact: Dr. Kaiyu Guan (kaiyug at illinois.edu)
and Dr. Jinyun Tang (jinyuntang at lbl.gov) for more information.

The University of Illinois is an Affirmative Action/Equal Opportunity
Employer. The administration, faculty, and staff embrace diversity and are
committed to attracting qualified candidates who also embrace and value
diversity and inclusivity. Visit www.inclusiveillinois.illinois.edu.
