We are hiring:

Title: Postdoc functional & anatomical connectivity (f/MRI) of attention control.

 

We would like to announce a post-doctoral researcher opening at Jane & Terry Semel Institute for Neuroscience and Behavior at University of California Los Angeles, with focus on functional and anatomical connectivity of attention control. The position is part of a broader multimodal neuroimaging project on attention and working memory deficits in ADHD conducted at UCLA’s world-class Staglin One Mind Center for Cognitive Neuroscience.

 

Duties & Responsibilities

  • Perform MRI analyses of activity & functional connectivity in task-related and resting state data, as well as of structural connectivity in DTI data
  • Independently acquire f/MRI data, including using cutting-edge concurrent EEG-fMRI techniques
  • Develop manuscripts and presentations for the dissemination of research

 

Qualifications

  • Ph.D. in psychology, cognitive neuroscience, biomedical/electrical engineering or a related field
  • Strong analytical skillset and proficiency with one or more major neuroimaging software tools (FSL, Freesurfer, SPM, AFNI etc.). Comfort with Matlab, R, Python or other programming languages is a plus.
  • Familiarity with Unix/Linux environment and comfort working in diverse computing environments including high-performance computing clusters
  • Interest in or experience with EEG is an asset, though not a requirement

 

Excellent communication skills, initiative, problem solving, and attention to detail are imperative. The position offers a vibrant working environment, as well as ample opportunity to participate in collaborative and independent research. For inquiries please contact Agatha Lenartowicz (alenarto at g dot ucla dot edu).

 

OUR RESEARCH:

Attention Control...
Attention control is the interplay of processes that determine what we attend to and what we ignore. My research aims to understand the brain mechanisms that govern these processes. Attention control has tremendous influence on daily life. Our ability to focus and ignore distractions impacts school and work performance, and in this way impacts personal success. It dictates self-control, our ability to resist distraction or temptation and do "something else”. It contributes to meta-awareness, our ability to observe our own behaviors and make appropriate changes. 
By understanding the dynamics of attention control processes we may be better able to provide concrete strategies for rehabilitation of depression, ADHD, and addiction. The supposedly increasing “inattentiveness” and “multi-tasking” that plagues the technology-overloaded generations of the Western world will inevitably have direct effects on the future health and norms of society. 

Research Questions…

  • MechanismsWhat are the neural dynamics - time course and within network interactions - by which attending and ignoring is implemented in the brain? What is the contribution of other systems, such as those that determine internal states (e.g., fatigue, anxiety, arousal, vigilance) to these neural dynamics?
  • DeficitsBy what mechanisms can attention control be disrupted, contributing to deficits such as ADHD (collaborating with Dr. Sandra Loo)? How is attention control sustained for prolonged periods of time? How and why does it get disrupted?
  • RehabilitationHow can attention control mechanisms be improved, such as through training (collaborating with Dr. G. Simpson) or relaxation (e.g., yoga, meditation, exercise)?

Methodology...
To answer these question I combine multi-modal neuroimaging technology (f/MRI, EEG) with multivariate analytical techniques. I am currently working with Dr. Mark Cohen to evaluate the utility of simultaneously recorded fMRI and EEG for analytically delineating the spatio-temporal profile of neural activity.
