Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

This work supports multi-institutional collaborations. How do you share data and coordinate with chemists and imaging partners at other sites?

What they are checking: Whether they communicate clearly and keep consistent methods across a team spread across institutions.

Tell me about a time you led an assay development project from start to a usable method.

What they are checking: Whether they can lead discovery work independently, which the role expects.

What would you do

Your autoradiography signal doesn't match the immunostaining on adjacent sections. How do you figure out why?

What they are checking: Whether they troubleshoot carefully, considering tissue quality, antibody specificity and nonspecific binding.

How would your binding data guide which compounds move forward as leads?

What they are checking: Whether they understand how their results feed into lead compound decisions and later imaging studies.

About the work

Walk me through how you'd set up an autoradiography assay to test whether a new PET tracer binds alpha-synuclein aggregates in human brain tissue.

What they are checking: Whether they can design a tissue-based binding assay with proper controls and tissue selection.

How do you show that a radioligand is specific for one aggregate, like alpha-synuclein, and not tau or amyloid beta?

What they are checking: Whether they understand that off-target binding is the main hurdle in neurodegeneration tracer development.

Explain how you'd run a competition binding assay and what you'd get from it.

What they are checking: Whether they know how to measure binding affinity, such as Ki or IC50, and interpret the results.

What's your experience with surface plasmon resonance, and how would you use it alongside tissue assays?

What they are checking: Whether they can use SPR to measure binding kinetics and connect it to results in real tissue.

How do you biochemically extract pathological proteins like sarkosyl-insoluble aggregates from brain tissue?

What they are checking: Whether they have hands-on experience preparing materials for binding studies.

What radiation safety practices do you follow when working with radioligands?

What they are checking: Whether they handle radioactive materials safely and follow licensing and dosimetry rules.

As published by University of Wisconsin-Madison.

Current Employees: If you are currently employed at any of the Universities of Wisconsin, log in to Workday to apply through the internal application process. Job Category: Academic Staff Employment Type: Regular Job Profile: Scientist I Job Summary: The Nirschl and Kolb laboratories at the University of Wisconsin–Madison invite applications for a Scientist I or II to contribute to the discovery and development of novel PET imaging tracers targeting pathological protein aggregates in neurodegenerative diseases, including Parkinson’s disease, Alzheimer’s disease, frontotemporal dementia, and ALS. These efforts support multi-institutional collaborations focused on improving early diagnosis and therapeutic development. The successful candidate will lead discovery/optimization by setting up and executing custom tissue-based assays, including autoradiography and radioligand binding assays, competition assays, and immunoassays or immunostaining, to evaluate compound binding affinity and specificity in human and animal biospecimens. Additional responsibilities include radioligand displacement studies, immunohistochemical validation, and biochemical extraction of pathological proteins from brain tissue. The role also involves conducting surface plasmon resonance (SPR) experiments to quantify molecular interactions. These efforts are critical to lead compound optimization and translational imaging biomarker validation. Applicants should have demonstrated expertise in tissue assay development, protein biochemistry, or molecular imaging and the ability to work in a collaborative, interdisciplinary environment. We seek applicants with a track record of outstanding research accomplishments and an ability to work in a highly collegial and collaborative academic environment. Candidates must meet eligibility requirements for appointment as Scientist I or II under the UW School of Medicine and Public Health guidelines. It is expected that the successful applicant will have a broad knowledge base in bioassay development, including: • Tissue homogenization, biochemical extraction and purification of pathological proteins from brain tissue samples, • Autoradiography assays using tissue slices or filter binding assays with tissue homogenates enriched for specific proteins/subcellular fractions, • Surface Plasmon Resonance measurements for assessing molecular interactions, • Biostatistical and computational analysis skills to inform Structure-Activity Relationship (SAR) and accelerate hit-to-lead development, • Histopathological characterization of brain tissue samples.
