As a visiting researcher at Lawrence Berkeley National Laboratory (Berkeley Lab), I am harnessing the unique opportunities here to propel my PhD research in astroparticle physics. My focus is on high-energy muons and their interactions in the atmosphere, particularly within the scope of the IceCube Neutrino Experiment. This experience has been pivotal in enhancing my technical expertise, collaborative abilities, and innovative thinking.The research environment at Berkeley Lab offers unparalleled advantages. Access to state-of-the-art facilities and high-performance computing resources has deepened my understanding of computational techniques and dataset management. Collaborating with leading scientists from diverse fields such as particle physics, atmospheric sciences, and data science has broadened my perspective, enabling me to contribute to groundbreaking solutions in high-energy physics.The hands-on experience with advanced detection and data acquisition technologies has significantly sharpened my skills in experimental design, data processing, and technology integration. Moreover, the dynamic and intellectually stimulating environment at Berkeley Lab has refined my problem-solving and critical thinking abilities, while also improving my scientific communication.Networking has been another key aspect of my time at Berkeley Lab. The connections I’ve made with top researchers globally are invaluable for my future career. The lab’s culture of innovation encourages creative thinking and the exploration of new ideas, which has inspired me to develop novel approaches to studying high-energy muons, further contributing to the field of astroparticle physics.Overall, my experience at Berkeley Lab has not only advanced my research but also helped me develop a robust skill set in data analysis, collaboration, and technological innovation—essentials for progress in astroparticle physics.

As a PhD student in physics, my research in the IceCube Neutrino Experiment focuses on high-energy muons and their interactions in the atmosphere. These muons, produced by cosmic rays colliding with the Earth’s atmosphere, are key to understanding cosmic ray sources and particle interactions at extreme energies.My work involves analyzing atmospheric muons, studying their production, propagation through Antarctic ice, and their role as background noise in neutrino detection. I develop and refine models that simulate cosmic ray interactions in the atmosphere, which are crucial for interpreting IceCube data and understanding atmospheric processes.I also focus on data processing and optimization, using advanced techniques like machine learning to accurately identify high-energy muons and reduce background noise, improving the precision of neutrino detection. Collaboration is a significant part of my role, as I work with global researchers to enhance muon detection accuracy and contribute to joint analysis projects.Beyond research, I supervise Bachelor’s and Master’s students, teach courses in astroparticle physics, and present my findings at conferences. I publish in peer-reviewed journals and mentor junior researchers, contributing to the scientific community.Additionally, I explore technological innovations to enhance IceCube’s detection capabilities by integrating advanced computational tools to study muon interactions. My research contributes to a deeper understanding of the universe’s most energetic processes, focusing on high-energy muons in the search for astrophysical neutrinos.

As a student assistant, I took on diverse responsibilities, including supervising physics lab courses, leading tutorial groups in three different subjects, and working as a web administrator.In the physics lab courses, students were required to independently prepare, set up, conduct, and analyze experiments, culminating in a scientific report. My role involved overseeing the entire experiment process, from setup to the evaluation of their reports, ensuring both the experimental procedure and documentation met high academic standards.As a tutorial group leader, I facilitated weekly sessions in both theoretical and experimental physics. I designed and assigned problem sets that students needed to complete as part of their exam qualification. I then graded these assignments and conducted weekly review sessions, where I guided students through the solutions and key concepts in a classroom setting.In my role as a web administrator, I revived an older PHP project that is used internationally by the MAGIC and LST collaborations for conference management. This involved troubleshooting legacy code and bringing the system back online, ensuring its continued functionality for the collaboration’s needs.

As a self-employed financial advisor with tecis AG, I focus on delivering personalized financial planning and advisory services tailored to each client’s goals. My approach is designed to help individuals achieve financial stability and long-term growth.Certified as an insurance broker (Versicherungsvermittler) under § 34 d Abs. 1 GewO, I provide expert guidance on selecting the right insurance coverage. My work involves comprehensive analysis of clients’ financial situations, developing customized plans that cover retirement, investments, insurance, and wealth management. I help clients build diversified investment portfolios aligned with their long-term objectives, considering market trends and economic conditions.I also specialize in risk management, using my certification to assess risks and recommend appropriate insurance products to protect clients’ assets and income. Retirement planning is another key area where I assist clients in securing a comfortable future by analyzing income, recommending pension plans, and optimizing tax-advantaged accounts.Client education is central to my practice. I empower clients to make informed financial decisions by providing educational sessions and resources. Compliance with regulatory guidelines and upholding the highest ethical standards ensure that all my recommendations are in the clients’ best interests.Building strong, lasting relationships with clients is a priority for me. I offer continuous support, regularly reviewing and adjusting financial plans to adapt to changing circumstances. Through my work with tecis, I am committed to helping individuals and families achieve financial security. My holistic approach, market expertise, and dedication to client service allow me to provide valuable, tailored guidance to meet diverse financial needs.
