Balancing act: An autoethnographic study of one medical educator's first year as a mentor

Anatomical Sciences Education, EarlyView.
Abstract Novice faculty mentors often struggle with the transition from mentee to mentor. Although they may face similar challenges, each mentor's experience and journey of professional identity formation is unique, influenced by their background, experiences, relationships, and context.

Data, not documents: Moving beyond theories of information‐seeking behavior to advance data discovery

Journal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 649-664, April 2025.
Abstract Many theories of human information behavior (HIB) assume that information objects are in text document format. This paper argues four important HIB theories are insufficient for describing users' search strategies for data because of assumptions about the attributes of objects that users seek.

Statistical MIMO beam codebook design for mmWave transmissions

EURASIP Journal on Wireless Communications and Networking, 2018
We propose a novel method for constructing beam codebooks, i.e., a set of beamforming weights, to be used for beam sweeping and data transmission in mmWave massive MIMO channels.

Essential work, invisible workers: The role of digital curation in COVID‐19 Open Science

Journal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 703-717, April 2025.
Abstract In this paper, we examine the role digital curation practices and practitioners played in facilitating open science (OS) initiatives amid the COVID‐19 pandemic. In Summer 2023, we conducted a content analysis of available information regarding 50 OS initiatives that emerged—or substantially shifted their focus—between 2020 and 2022 to address ...

“You're this person who's providing light”: Embodied responses to information loss and transition within LGBTQIA+ communities

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This paper reports on findings from 15 semi‐structured interviews with LGBTQIA+ individuals within the United States who have experienced the loss of one or more LGBTQIA+ information spaces. The paper specifically focuses on how such losses occurred and the information transitions experienced by the participants in response to this loss ...

“Basic human things”: Investigating vehicle residents' continually fractured (information) landscapes

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This ethnographic study explores vehicle residents' information practices in the United States (US). Vehicle residents are people whose primary means of housing is a vehicle. This work builds on previous research encompassing transitions and fractured (information) landscapes. Using fractured information landscapes as the theoretical framework,
