Subgroups

As the Biophysical Society continues to grow, the Society's Subgroups allow members to meet and interact within more focused areas in smaller groups. Subgroups hold scientific symposia and business meetings each year on the Saturday that starts the Annual Meeting. They also sponsor several awards, including the Student Research Achievement Awards (SRAA) Poster Competition. Membership to the Society's Subgroups is open to all members.

You may become a part of any of Subgroups listed below by becoming a BPS member. If you are existing member and would like to make changes to your Subgroup, View or Change your Subgroup(s)

Macromolecular Machines & Assemblies

(formerly Molecular Biophysics)



The Macromolecular Machines & Assemblies Subgroup (formerly Molecular Biophysics)  is comprised of members with interests that span all areas of molecular biophysics. In particular these areas include:

  • Structures, conformational switching, and conformational dynamics of biological macromolecules and their supramolecular assemblies
  • Thermodynamics and kinetics of the processes that these macromolecules undergo, such as DNA replication, protein synthesis, self-assembly, self-organization, molecular recognition and binding, signaling, catalysis, and metabolic control
  • Responses of biological macromolecular systems to various imposed perturbations, such as (a) changes in temperature, ligand concentration, ionic strength, water activity, solvent polarity, hydrostatic pressure, osmotic pressure of volume-exclusion agents, denaturant concentration, and mutation of the primary sequence, (b) electric, magnetic, electromagnetic and hydrodynamic flow fields, and (c) stretching, bending and torsional strain
  • Diffusive, field-induced, and convective transport of both small and large molecules under various conditions, or through various media or channels of biophysical, biochemical or biological relevance
  • Experimental methods (physical, molecular biological, and chemical) that are used to isolate and characterize biological macromolecules and assess their relevant properties, or to achieve particular assembly or folding targets
  • Theoretical and computational methods used to interpret previous results and future experiments

 

Annually, the Subgroup holds a topical symposium, which is organized by the current Subgroup chair.

 

In order to join the Macromolecular Machines & Assemblies Subgroup, you must be a member of the Society.

Macromolecular Machines & Assemblies Bylaws

 

Article I
Purpose: The purpose of the Macromolecular Machines & Assemblies (MMA) Subgroup (formerly Molecular Biophysics) is to provide a forum for the dissemination of information in the area of biopolymers, macromolecular structure, dynamics and interactions.

 

Article II
Membership: Members of the Biophysical Society may join the Macromolecular Machines & Assemblies Subgroup; nonmembers of the Biophysical Society are welcome to attend MMA Subgroup symposia but are unable serve as Officers of the Subgroup, or vote.

 

Article III

Meetings: Business meetings of the Subgroup membership shall be held in connection with or in close proximity to the Annual Scientific Meeting of the Biophysical Society. If any matters come up that require a vote at any time of year, Subgroup members can transact Subgroup business by a virtual vote. For virtual votes, decisions shall be made by two-thirds of the Subgroup members voting on the measure.

 

Article IV
Officers: The Officers of the Subgroup will be the Subgroup Chair, Chair-Elect, Past-Chair, Secretary-Treasurer, Postdoc Representative, and Student Representative. The Chair-elect shall serve one year as such followed by one year as Chair. The Secretary-Treasurer shall be elected for a term of two years. The Postdoc and Student Representatives shall serve one year. These positions have the following responsibilities:

 

Chair, Chair-Elect, & Past Chair: As chair, will organize and conduct the annual Subgroup meeting; apprising the Biophysical Society of the activities and needs of the Subgroup; advising the Society on matters related to the Subgroup; promoting and overseeing the Student Research Achievement Award (SRAA) competition; communicating with the Society concerning meeting plans and public communications (flyers, announcements, newsletter reports, etc.); and participating in activities that benefit the Subgroup and Society. Responsible for the Subgroup meeting all deadlines established by the Subgroup Manager and monitoring all efforts that contribute to the Subgroup Report Card. The past chair will help provide continuity, offer advice, and assist in the work of the executive committee.

 

Secretary-Treasurer: Will work with the Society to manage Subgroup membership, budgets, keep up to date with financial information and sponsorships, and will work with the Chair to carry out necessary correspondence and other organizational tasks.

 

Postdoc Representative: will contribute the perspective of their peers on topics related to Subgroup membership.

Student Representative: will contribute the perspective of their peers on topics related to Subgroup membership. 

Article V

Eligibility for Office: Only voting members of the Macromolecular Machines & Assemblies Subgroup may be elected to Subgroup leadership positions. If an elected officer does not become a member prior to the Annual Meeting where they would be taking office, the second runner-up candidate shall assume the position instead. The runner up must also be a BPS member and a member of the Subgroup in order to assume office. In order to serve as a regular Subgroup Officer, the member must be a Regular, Emeritus, or Early Career member of BPS. Graduate students/Postdocs can only serve if the Subgroup has a designated trainee position, in which case the position title will reflect the career stage of eligible members. Members may not be elected to the same position in the Subgroup more than every five years.   

 

Article VI
Elections: Elections must be held and concluded electronically two weeks prior to the Subgroup’s Business Meeting. The candidates for each office receiving the highest number of votes will be elected. In the case of a tie, the deadline will be extended for an extra three days. If the tie remains after three days, BPS staff will send out a new ballot with just the tied candidates to break the tie. The results will be announced to the Subgroup’s membership during the Subgroup’s Business Meeting. Officers will take office at the end of the annual business meeting held in conjunction with the Annual Meeting of the Biophysical Society. Interim vacancies in officers or councilors will be filled in accordance with Bylaw Article XVIII of the Biophysical Society.

 

Article VII

Executive Committee: The Executive Committee will be responsible for fulfilling the scientific and business obligations of the group. The Executive Committee will consist of the Officers. The affairs of the Subgroup shall be handled by the Officers in accordance with the policies determined by the Executive Committee and the Biophysical Society Council.

 

Article VIII

Nominating Committee: The Nominating Committee is responsible for soliciting nominations from Subgroup membership and for preparing the final slate of candidates. The members of the Executive Committee shall constitute the Nominating Committee. Nominations can come from anyone, with self-nominations also permitted. Ad hoc nominations shall also be allowed. Nominations will be received electronically no later than one month prior to the Subgroup’s Business Meeting. Nominees must accept their nomination prior to being placed on a ballot.

 

Article IX

Dissolution: The Macromolecular Machines & Assemblies Subgroup must be in accordance with the Biophysical Society’s constitution and bylaws, mission, values, goals, and operational guidelines. If not, the group will be placed on probation and may be dissolved at the discretion of the Council of the Biophysical Society.

 

Article X
Amendments to the Bylaws: Amendments can be proposed by any member of the Macromolecular Machines & Assemblies Subgroup, be approved by a two-thirds majority of the Subgroup’s Executive Committee, and be ratified in an electronic ballot by a majority of the members of the group voting.
