I am a postdoctoral researcher in astroparticle physics at the Institute for Cosmic Ray Research at the University of Tokyo. I do gamma-ray astronomy with Imaging Atmospheric Cherenkov telescopes and am member of the MAGIC and CTA collaborations. My current research focuses on indirect Dark Matter detection and development of a new data analysis software for Cherenkov telescopes, and I am involved in the commissioning of the first Large-sized Telescope of the CTA observatory.
My research interests include high-energy astrophysics, dark matter phenomenology, and cosmology.
in the Cherenkov Cosmic Gamma Ray group of Masahiro Teshima.
in the MAGIC/CTA group. Convener of the MAGIC astroparticle and fundamental physics working group.
Postdoctoral starting grant by the graduate school 1504 "Mass, Spectrum, Symmetry" of the German Research Foundation (DFG). Scientific coordination of the graduate school.
with Gernot Maier on the topic of Prospects for Galactic dark matter searches with the Cherenkov Telescope Array. Member of the VERITAS and CTA collaborations.
I work on the low-level analysis of calibrated MAGIC data using the ctapipe software. ctapipe will be the common analysis framework incorporating the various telescopes of the future CTA. By porting the MAGIC data format to this analysis software, the same air showers recorded by MAGIC can be conjointly analysed with the CTA-LST telescopes already or soon in the future located in close neighborhood to MAGIC.
The image shows an air shower event recorded by MAGIC in the field of view towards the Crab Nebula (red cross). The star symbols denote the location of nearby stars of magnitude lower than 6 by their Henry Draper Catalogue number. The event shows the Cherenkov light by most probably an electromagnetic shower created by a gamma ray orginating from the direction of the Crab Nebula.
I am a main author of the Clumpy code to model gamma-ray and neutrino signals from astrophysical Dark Matter targets. Clumpy offers a wide range of computations to be done; synthetic models of individual targets including Dark Matter substructure; a Jeans analysis module to infer Dark Matter budgets from kinematic data; and an extensive cosmology suite.
The image shows the gamma-ray intensity map from Galactic Dark Matter decay shown in Fig. 4, 2nd row, 2nd column of Galaxies 2019, 7(2), 60
I am convener of the MAGIC astroparticle and fundamental physics working group, and involved in various projects to constrain particle Dark Matter candidates with MAGIC observations; in particular, from observations of the Galactic Centre region.
I am co-chair of the CTA task-force to study prospects for detecting gamma-ray emission from Dark Matter and diffuse intra-cluster cosmic rays with CTA. I am also interested in exotic physics signals from Galaxy clusters, like oscillations of axion-like particles.

I am member of the "Netzwerk Teilchenwelt" ("Network Particle World"), a program funded by the German ministry for education to foster the interest for particle- and astroparticle physics of school kids by workshops and courses ("Masterclasses") in their schools or in the institute. Detailed descriptions of the available courses can be found here.
