EXHIBIT 31.2

           CERTIFICATION PURSUANT TO 18 U.S.C. SECTION 1350 AS ADOPTED
            PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

     1.   I have reviewed this quarterly report on Form 10-QSB of Biomoda, Inc.

     2.   Based on my  knowledge,  this  quarterly  report  does not contain any
          untrue  statement of a material  fact or omit to state a material fact
          necessary to make the statements  made, in light of the  circumstances
          under which such  statements were made, not misleading with respect to
          the period covered by his quarterly report;

     3.   Based on my knowledge,  the financial  statements and other  financial
          information  included in this quarterly report,  fairly present in all
          material respects the financial  condition,  results of operations and
          cash flows of the registrant as of, and for, the periods  presented in
          this quarterly report;

     4.   I am responsible for establishing and maintaining  disclosure controls
          and procedures (as defined in Exchange Act rule 13a-14 and 15d-14) for
          the registrant and have:

          a.   designed such  disclosure  controls and procedures to ensure that
               material  information  relating to the registrant,  including its
               consolidated  subsidiary  is made  known to us by  others  within
               those  entities,  particularly  during  the  period in which this
               quarterly report is being prepared;

          b.   evaluated  the  effectiveness  of  the  registrant's   disclosure
               controls and  procedures as of a date within 90 days prior to the
               filing date of this quarterly report (the "Evaluation Date"); and

          c.   presented  in this  quarterly  report our  conclusions  about the
               effectiveness of the disclosure  controls and procedures based on
               our evaluation as of the Evaluation Date;

     5.   I  have  disclosed,  based  on  our  most  recent  evaluation;  to the
          registrant's  auditors and the  registrant's  board of  directors  (or
          persons performing the equivalent function);

          a.   all  significant  deficiencies  in the  design  or  operation  of
               internal  controls which could adversely  affect the registrant's
               ability to record,  process,  summarize and report financial data
               and have  identified for the  registrant's  auditors any material
               weakness in internal controls; and

          b.   any fraud,  whether or not material,  that involves management or
               other employees who have a significant  role in the  registrant's
               internal controls; and

     6.   I have  indicated in this  quarterly  report whether or not there were
          significant  changes in  internal  controls or in other  factors  that
          could significantly affect internal controls subsequent to the date of
          our most recent  evaluation,  including  any  corrective  actions with
          regard to significant deficiencies and material weaknesses.
