* Alexander von Humboldt Stiftung Prize (1989, 1992)
* Max Planck Research Prize, jointly awarded with Professor Peter Haasen (1993)
* Robert Franklin Mehl Medal (TMS, 2011)
Additionally, his research from 1968 to 1977 was rated among the top twenty most highly rated major achievements sponsored by the National Science Foundation in materials science, as identified by a MITRE evaluative study of Materials Research Laboratory Programs. He also received the National Science Foundation Creativity Extension Award (2001–2003) and an IBM Faculty Research Award (2010–2011). In February 2009, Seidman was honored with a two-and-a-half-day symposium at the annual TMS meeting in San Francisco, California. From 2011 to 2012, he served as a Sackler Lecturer at the Mortimer and Raymond Sackler Institute of Advanced Studies at Tel Aviv University.

## Research

Seidman has authored over 500 high-impact peer-reviewed publications focusing on the atomic-scale study of materials. His research enables advancements in applications such as nanotechnology, additive manufacturing, quantum computing, alternative green energy solutions, and structural materials for aerospace, automotive, and defense industries.

## Legacy and impact

Seidman's innovations in materials characterization, particularly through atom-probe tomography, have had profound implications across industries, from aerospace to nanotechnology. His mentorship and leadership continue to influence future generations of scientists and engineers. Seidman is the director of the Northwestern University Center for Atom-Probe Tomography (NUCAPT), which is a core facility of Northwestern University and the National Science Foundation funded Materials Research Science and Engineering Center. NUCAPT was founded during the summer of 2004 and has been operational on a full-time basis since late December 2004. It is a completely open facility for all researchers internal and external to Northwestern University and it has attracted researchers from universities and national laboratories in the US as well as researchers from around the world. NUCAPT is constantly improving its infrastructure as well as developing new techniques for analyzing the data collected using the local-electrode atom-probe (LEAP) tomograph on which NUCAPT is based. The facility recently upgraded its LEAP 4000 instrument to the cutting-edge LEAP 5000XS (Cameca, Madison, Wisconsin,) which combines new flight path technology with enhanced detector performance to offer an improved field-of-view while achieving unprecedented detection efficiency of about 80%, the highest of any such analytical technique. This is a unique facility at Northwestern and the US, which has attracted a significant number of professors to explore new avenues of research based on the use of the LEAP tomograph as well as researchers from other universities and national laboratories, Argonne National Laboratory, Pacific Northwest National Laboratory, Oak Ridge National Laboratory.
