Job Summary

The Tan research group ( within the Department of Biomedical and Health Informatics at The Children’s Hospital of Philadelphia is seeking an enthusiastic candidate for a bioinformatics scientist position. The laboratory is interdisciplinary and highly collaborative, utilizing both computational and experimental approaches to study gene regulation in normal and disease development. We have pioneered multiple computational algorithms for regulatory genomics, epigenomics, and network biology. Key responsibilities include developing and maintaining interactive bioinformatics databases, collecting and analyzing genomics datasets, bioinformatics data analysis, summarizing results and preparing reports, and contributing to manuscripts/publications.
The desired candidate should have a BS or MS in bioinformatics or related fields such as statistics and computer sciences. Strong statistical and computer programming (R, Perl/python, JavaScript, C/C++) skills are essential. Previous research and classroom course work in bioinformatics is preferred.

Job Responsibilities

Pre-Analysis (40%): Contributes to the maintenance and development of bioinformatics tool portfolio by developing knowledge of internally developed systems, open-source programs, and commercial applications. Provides efficient data management support.

  • Works with bioinformatics group members to develop functioning pipelines upstream of customized analysis workflows.
  • Maintains pipelines by staying current with evolving algorithms and standards and incorporating into pipeline.
  • Executes robust development testing for commonly used applications such as data processing pipelines.
  • Optimizes performance of applications by working with scientific computing and information systems groups to optimize hardware/software parameters.
  • Defines and prioritizes requirements for pipeline development over time to incorporate new technologies and platforms via functional communication with bioinformatics group members and bioinformatics end users.
  • Identifies appropriate open-source and commercial products that serve needs of pipeline and/or customized analyses of end users.
  • Implements and maintains commercial and open-source software for common bioinformatics and genomics data analysis.
  • Implements, updates and maintains locally stored data resources required for various analysis tasks.
  • Provides ad hoc support and one-on-one and group-based training on key bioinformatics software, features, and workflows.
  • Provides efficient data management support including file transfers, data formatting and manipulation, and basic integration of data from a variety of experimental and reference resources.
  • Develops and maintains working relationship with data providers such as sequencing cores within CHOP and infrastructure groups such as information systems.
  • Continually keeps abreast of evolving data generation platform fundamentals, file-specific information representation, and strategic application of code base to optimize value of data.
  • Maintains working knowledge of available commercial and openly accessible knowledge bases as they apply to bioinformatics analysis.

Job Responsibilities (Continued)

Coding (30%): Codes and generally supports both ad hoc, single task applications and larger pipeline applications that may combine multiple 3rd party and internally developed applications for genomics/proteomics/other complex data types and projects.

  • Implements, maintains, and regularly contributes to formal and bioinformatics group-centralized code management system.
  • Adopts appropriate forking and other strategies for robust code development. Apply to general bioinformatics group code base.
  • Adopts best practices for code development consistent with larger bioinformatics group. This includes choice of language based on the type of solution being developed, the likely life cycle and downstream usage of the resulting application, and integration with other systems.
  • Ensures that all routinely used tools (e.g. those included in shared analysis pipelines) are versioned and managed through a source control system.  
  • Ensures that configuration files that provide parameters to algorithms and analysis software are versioned and managed through a source control system.
  • Develops and implements automated data-driven testing processes that test reproducibility of results between versions of pipeline software.
  • Develops and implements automated deployment processes that build and configure systems from source control repositories, eliminating the need to manually modify configuration files.
  • Regularly documents code, troubleshoot, and provide training when necessary.


Data Analysis (10%): Analyzes data of high complexity by applying sound statistical and commonly accepted bioinformatics methods to -omics data under supervision from mentors and peers.

  • Develops robust analysis plans under supervision.
  • Incorporates QA/QC in analysis workflows.
  • Delivers analytical endpoints such as feature identification, annotation, characterization, prioritization, etc.
  • Reports results using, primarily, spreadsheets and, secondarily, abstracted materials such as slides and visuals.


Collaboration (10%): Works with both bioinformatics group members and end users/clients to understand specific needs in bioinformatics and end user-specific domains.

  • Attends group and team meetings and contributes primarily factual information regarding processes and approach.
  • Defers to mentors and peers in establishing relationships, but works within boundaries to accomplish analytical goals.


Academic Output (10%): Contributes to presentations, grants, and manuscripts under supervision by mentors and peers.
