PhD positions at Graz University of Technology

Graz University of Technology offers two PhD positions in the Institute of Geometry. The research area is computational geometry and topology. Possible topics include topological data analysis, connections of discrete geometry and topology, design and analysis of algorithms in computational topology.

We offer a 4-year university assistant position (30 h/week) with a net salary of approximately 23,000 EUR per year. The starting date for both positions is Oct 1 2021.

We are looking for outstanding students with a master’s degree in Mathematics/Computer Science or a closely related field. Knowledge in at least one of the fields computational geometry or computational topology is a plus. Basic knowledge in algebraic topology, theoretical computer science, and programming skills, in particular in C++ or python, are also desirable.

The position includes teaching duties as teaching assistant, both for students of mathematics and others. The ability to teach in German is an advantage.

Applications should include:
* a letter of application and motivation
* a detailed curriculum vitae
* a recent academic transcript
* a copy of the master thesis (or a current draft)
* a reference letter (for instance, by the Master thesis supervisor – can be sent separately)
* email addresses of additional references (if applicable)

and should be sent until May 26 2021 using the reference number 5070/21/003 to bewerbungen.mpug@tugraz.at

Further questions regarding the positions should be directed to Michael Kerber (kerber@tugraz.at).

Postdoc in Topological Neuroscience, University of Delaware

The Department of Mathematical Sciences at the University of Delaware invites applications for a postdoctoral researcher position beginning on or around July 1, 2021. The postdoctoral researcher will work with Dr. Chad Giusti to develop novel methods for understanding how brain networks encode and process information using techniques from topology, algebra, and geometry. The position carries a competitive salary and benefits, and offers interdisciplinary research and training opportunities in applied topology and neuroscience. Teaching opportunities are likely to be available but teaching is not required.

Applicants should have a PhD in mathematics or related discipline, with a strong background in algebraic or combinatorial topology. Programming experience or experience with data analysis are preferred. Background in neuroscience, biology, or applied topology are a plus, but are not required so long as the applicant is excited to learn. Some travel for conferences and collaborative research is expected. The position is renewable annually for three years.

The official ad is in the works and will be up on mathjobs shortly. Applications will be reviewed on a rolling basis and accepted until the position is filled. Applicants are encouraged to contact Chad Giusti (cgiusti@udel.edu) with questions.

CfP: CGTA Special Issue on Algorithmic Aspects of Computational and Applied Topology

***** Call for papers – CGTA Special Issue on Algorithmic Aspects of Computational and Applied Topology *****

Computational Geometry is a forum for research in theoretical and applied aspects of computational geometry. The journal publishes fundamental research in all areas of the subject, as well as disseminating information on the applications, techniques, and use of computational geometry. Computational Geometry publishes articles on the design and analysis of geometric algorithms. All aspects of computational geometry are covered, including the numerical, graph theoretical and combinatorial aspects. Also welcomed are computational geometry solutions to fundamental problems arising in computer graphics, pattern recognition, robotics, image processing, CAD-CAM, VLSI design and geographical information systems.

This special issue is dedicated to original contributions in the general area of computational and applied topology. This includes, but is not limited to, progress on theory, algorithms and complexity analysis, implementation, and experimental study of problems in areas such as persistent homology, topological data analysis, low dimensional topology, homotopy theory, and topological combinatorics.

This special issue will be edited by Erin Wolf Chambers, Brittany Terese Fasy, and Clément Maria.
