Berger A, Edwards E, Nembach H, Karis O, Weiler M, Silva T
Phys Rev B . 2025 Jan; 98(2. PMID: 39811783
Understanding the evolution of spin-orbit torque (SOT) with increasing heavy-metal thickness in ferromagnet/normal metal (FM/NM) bilayers is critical for the development of magnetic memory based on SOT. However, several experiments...

Dunn K, Matlock A, Funkenbusch G, Yaqoob Z, So P, Berger A
Biomed Opt Express . 2024 Feb; 15(2):973-990. PMID: 38404316
Angularly resolved light scattering (ALS) has become a useful tool for assessing the size and refractive index of biological scatterers at cellular and organelle length scales. Sizing organelle populations with...

Massie C, Knapp E, Awad H, Berger A
J Biomech . 2023 Nov; 161:111852. PMID: 37924650
While osteoporosis is reliably diagnosed using dual energy X-ray absorptiometry (DXA), screening rates are alarmingly low, contributing to preventable fractures. Raman spectroscopy (RS) can detect biochemical changes that occur in...

Dunn K, Berger A
J Biomed Opt . 2023 Aug; 28(8):086501. PMID: 37564163
Significance: Organelle sizes, which are indicative of cellular status, have implications for drug development and immunology research. At the single cell level, such information could be used to study the...

Madejski G, Ahmad S, Musgrave J, Flax J, Madejski J, Rowley D, et al.
Sustainability . 2023 Mar; 12(24). PMID: 36938128
To better understand the origin of microplastics in municipal drinking water, we evaluated 50 mL water samples from different stages of the City of Rochester's drinking water production and transport...

Dunn K, Elias T, Brown E, Berger A
Biomed Opt Express . 2022 Aug; 13(8):4236-4246. PMID: 36032574
Angularly-resolved light scattering has been proven to be an early detector of subtle changes in organelle size due to its sensitivity to scatterer size and refractive index contrast. However, for...

Chen K, Massie C, Awad H, Berger A
Biomed Opt Express . 2022 Jan; 12(12):7517-7525. PMID: 35003849
Spatially offset Raman spectroscopy (SORS) is able to detect bone signal transcutaneously and could assist in predicting bone fracture risk. Criteria for optimal source-detector offsets for transcutaneous human measurements, however,...

Massie C, Chen K, Berger A
Appl Spectrosc . 2021 Oct; 76(2):255-261. PMID: 34596460
Back-illuminated charged-coupled device (BI-CCD) arrays increase quantum efficiency but also amplify etaloning, a multiplicative, wavelength-dependent fixed-pattern effect. When spectral data from hundreds of BI-CCD rows are combined, the averaged spectrum...

Massie C, Knapp E, Chen K, Berger A, Awad H
J Biomech . 2021 Jan; 116:110243. PMID: 33485148
Bone fragility and fracture risk are assessed by measuring the areal bone mineral density (aBMD) using dual-energy X-ray absorptiometry (DXA). While aBMD correlates with bone strength, it is a poor...

Draham R, Dunn K, Berger A
Opt Lett . 2020 Dec; 45(24):6775-6778. PMID: 33325894
We report what is to our knowledge the first use of Fourier phase microscopy (FPM) to estimate diameters of individual single-micrometer beads and to classify cells based upon changes in...
